area & perimeter help!

Step-by-step explanation:

Remember: the midsegment is always parallel to the third side, and the length is half of the third side. (Third side = XY) Assuming that line segment XY is the length of the third side of the triangle, we can insert it into this equation:

[tex]m=\frac{AB}{2}[/tex]

Let's plug in XY for AB.

[tex]m = \frac{XY}{2}[/tex]

[tex]m=\frac{12}{2} \\[/tex]

[tex]AC=6[/tex]

Our final answer: AC = 6

Answer:

[tex] \boxed{ \bold{ \boxed{ \sf{12}}}}[/tex]

Option C is the correct option.

Step-by-step explanation:

Using PEMDAS rule :

Parentheses, Exponents , Multiplication , Division , Addition , Subtraction

Let's solve

[tex] \sf{3 \times (12 - 5) - 9}[/tex]

Subtract 5 from 12

⇒[tex] \sf{3 \times 7 - 9}[/tex]

Multiply the numbers

⇒[tex] \sf{21 - 9}[/tex]

Subtract 9 from 21

⇒[tex] \sf{12}[/tex]

Hope I helped!

Best regards!!

Answer:

21

Step-by-step explanation:

12/4.+18

The lcm is 4.

12+4(18) all divided by 4

12+72=84

84/4=21

Answer:

[tex] \frac{84}{4} \: or \: 21[/tex]

Step-by-step explanation:

[tex] \frac{12}{4} + 18 = \frac{12}{4} + \frac{18}{1} = \frac{12 + 72}{4} = \frac{84}{4} \: or \: 21 [/tex]

Criss cross the fraction and you will get the answer.

Answer:

Below

Step-by-step explanation:

Follow this rule:

● if the numbers multiplied together have the same signs, the product is a positive number.

● if the nupbers multiplied togethers have different signs, the product is a negative number.

Answer:

Step-by-step explanation:

anytime you multiply a positive+Positive= it equals a positive number  if you multiplying a negative + positive it will equal a negative even if the positive number is bigger for example 4 x -9= -36           9 x 4= 36      -9 x -4 = 36

Answer:

I got 109

Step-by-step explanation:

f(x)=5(x+4)-6     x=19

f(19)=5(19+4)-6

*Add 19 + 4 because it is in ()*     f(19)=5(23)-6

*Multiply because it is the first in the order of operations*    f(19)=115-6

*Now just subtract*      f(19)= 109

Answer:

8 bags

Step-by-step explanation:

Take the number of nuts and divide by the number of pounds in a bag

6 lbs  ÷ 3/4 lbs

Copy dot flip

6 * 4/3

8 bags

Answer:

[tex]\Huge \boxed{\mathrm{8 \ bags}}[/tex]

Step-by-step explanation:

We can solve the problem with algebra.

[tex]\displaystyle \frac{3}{4} x=6[/tex]

Let x be the number of bags.

Multiply both sides by [tex]\frac{4}{3}[/tex]

[tex]\displaystyle \frac{3}{4} x \cdot \frac{4}{3} =6 \cdot \frac{4}{3}[/tex]

[tex]x=8[/tex]

The number of bags is 8.

Answer:

9.375, or 10 bags, since he cant buy a part of a bag. Hope this helps!

Answer:

+ 80

Step-by-step explanation:

Given

(2 - x)(5 - 3x)(1 - 7x) ← expand the first two factors using FOIL

= (10 - 11x + 3x²)(1 - 7x)

Each term in the second factor is multiplied by each term in the first factor

= 10(1 - 7x) - 11x(1 - 7x) + 3x²(1 - 7x) ← distribute the 3 parenthesis

= 10 - 70x - 11x + 77x² + 3x² - 21x³ ← collect like terms

= - 21x³ + 80x² - 81x + 10

The coefficient of the x² term is + 80

Answer:

112x-280

Step-by-step explanation:

Answer: pemdas you solve each portion in the order of pemdas  parenthesis, exponents, multiplication, division, addition, and subtraction  so you would start with 2(5x)  than you would need to make both sides true so if you were to take 6 away from the left side of the equal sign you would need to do the same on the other side so put negative six on the right side

Step-by-step explanation:

Answer:

[tex]\huge \boxed{\mathrm{No \ solutions.}}[/tex]

Step-by-step explanation:

[tex]6-2|5x|=86[/tex]

Subtracting 6 from both sides.

[tex]-2|5x|=80[/tex]

Dividing both sides by -2.

[tex]|5x|=-40[/tex]

Solving for absolute value.

Absolute value cannot be less than 0.

There are no solutions.

Last month, Ed ate 9 apples, 5 bananas, 4 peaches, and 7 oranges. Find the ratio bananas to the total number of fruit. Then explain the meaning.

Step-by-step explanation:

first since there is 5 bananas it will be 5:_ and then the total so add up all the fruits

9+5+4+7=25 so

5:25

or

1:5

Answer:

Step-by-step explanation:

Given that:

Ken's prediction temperature for April 7C.

His prediction for May is 2C higher than April.

He attempts to use the number line to solve the problem.

On a number line, we have the origin at a given point zero, the positive x-axis to the right side, and the negative x-axis to the left side.

So, if Ken's starts from zero and move right to seven and the move units to the left, the error he made was moving 2 units to the left because he supposed to have continued in the right direction by moving 2 units forward. This is because moving to the left side will showing a decrease in the temperature by -2° C and he intends to have 2° C.

Hope it helps!

Answer:

The cup is a cooking measure of volume, commonly associated with cooking and serving sizes. It is traditionally equal to half a liquid pint in US customary units, or an amount between 200 mL and 250 mL (​1 ⁄ 5 and ​1 ⁄ 4 of a litre) in the metric system, which may vary due to location.

Answer:

the farmer has 242 apples left

Step-by-step explanation:

A = awnser

M= Monday

T= Tuesday

M= 242

T= 109

W = amount sold or 109

(M+T)-W= total amount left

use order of operations and add whats in the (   )

( 242+109 ) = 351 or ( M+T )

then you would use the sum of ( M+T ) and subtract W or 109 wich would then equal 242 so the equation

( 242+109 ) - 109 would equal 242 or ( M+T ) - W = A

Answer:

The second term is, t₂ = 20.

Step-by-step explanation:

The recursive function described is as follows:

[tex]t_{n}= t_{n-1}-t_{n-2}[/tex]

Given:

[tex]t_{8}=20\\\\t_{6}=13[/tex]

Compute the 7th term as follows:

[tex]t_{8}= t_{7}-t_{6}\\\\t_{7}=t_{8}+t_{6}\\\\t_{7}=20+13\\\\t_{7}=33[/tex]

Compute the 5th term as follows:

[tex]t_{7}= t_{6}-t_{5}\\\\t_{5}=t_{6}-t_{7}\\\\t_{5}=13-33\\\\t_{5}=-20[/tex]

Compute the 4th term as follows:

[tex]t_{6}= t_{5}-t_{4}\\\\t_{4}=t_{5}-t_{6}\\\\t_{4}=-20-13\\\\t_{4}=-33[/tex]

Compute the 3rd term as follows:

[tex]t_{5}= t_{4}-t_{3}\\\\t_{3}=t_{4}-t_{5}\\\\t_{3}=-33+20\\\\t_{3}=-13[/tex]

Compute the 2nd term as follows:

[tex]t_{4}= t_{3}-t_{2}\\\\t_{2}=t_{3}-t_{4}\\\\t_{2}=-13+33\\\\t_{2}=20[/tex]

Thus, the second term is, t₂ = 20.

Answer:

The correct option is Segment Addition Postulate

Step-by-step explanation:

The segment addition postulate states that where there are two points on a line A and C and a third point B can only be located on the line segment AB if and only if the the distances between point A and point B as well as the distance between point B and point C satisfy the equation AB + BC = AC

Therefore, given that in the figure,  the point B is in between point A and point C on segment AC then AB + BC

Similarly, AD = AE + ED.

Answer:

b=0       would appreciate brainliest

Step-by-step explanation:

Otherwise, no solution for this equation. You cannot isolate the variable a; its solution value can be anything, but you still find b=0.

2a+b=2a

b+2a=2a

b+2a-2a=2a-2a

b+0=0

b=0

1.   Which becomes 2(1) + 0 = 2(1)

2.    2 + 0 = 2 :

3.    2 = 2. Here we can observe the equality.

Answer:

24

Step-by-step explanation:

12 * 2 = 24

Answer:

a=m-n

(Add n to both sides)

a+n=m-n+n

(The -n and +n cancel out, on the right side of the equation)

a+n=m

(Now subtract a from both sides)

a+n-a=m+a

(The +a and -a cancel out, on the right side of the equation)

n=m+a

Answer:

[tex]\huge \boxed{n=-a+m}[/tex]

Step-by-step explanation:

[tex]a=m-n[/tex]

Adding [tex]n[/tex] to both sides.

[tex]a+n=m-n+n[/tex]

[tex]a+n=m[/tex]

Subtracting [tex]a[/tex] from both sides.

[tex]a+n-a=m-a[/tex]

[tex]n=m-a[/tex]

Answer:

A scale copy of a figure is a figure that is geometrically similar to the original figure. This means that the scale copy and the original figure have the same shape but possibly different sizes. First you have to look at one of the sides of the scaled copy. If they are divisible by the numbers in the original shape, then try and see if the others sides of the scaled copy are scaled by the same factor. If they are, then they are a scaled copy.
