AADE related to AABC? How do you know?

Answer:

(x + 9)(x + 2 )

Step-by-step explanation:

Sum =11

Product = 18

Factors = 9 , 2

When you multiply (9*2 = 18) and when you add (9 +2 = 11).

x² + 11x + 18 = x² + 9x + 2x + (9*2)

                   =x(x + 9) + 2(x + 9)

                  = (x + 9)(x + 2 )

Answer:

(x+9) (x+2)

Step-by-step explanation:

x^2+11x+18

x^2+9x+2x+18

x(x+9)+2(x+9)

(x+9) (x+2)

Answer:

the car travels faster

Step-by-step explanation:

Since the motorcycle has traveled 300 feet, and the car has traveled 600 feet, we will divide 600 by 2

600 divided by 2 = 300

Hank would have traveled 300 feet in 10 seconds

Andy traveled 300 feet at 12 seconds

Therefore Hanks car travels faster

Answer:

The car travels faster

Step-by-step explanation:

600 ft per 20 secs

How many feet in one sec?

600/20 = 30

Hank's car = 30 feet per second

300 feet in 12 sec

How many feet in one sec?

300/12 = 25

Andy's motorcycle = 25 feet per second

have a great day ahead

Step-by-step explanation:

To work out the scale factor, divide one of the sides from the larger shape from the smaller shape so:

15/6 = 2.5

So your scale factor would be 2.5

And to check this, multiply 2.5 by 6 and u should get 15, so you know it is correct! :)

Answer:

2x+4y= 24

x≥3

y≤2

Step-by-step explanation:

Given data

total expenses= $24

let the number of tickets be x

and the number of rides be y

Tickets cost $2 each, and ride tickets cost $4

Hence the expression for the situation is given as

2x+4y= 24

x≥3

y≤2

Hey there!

The answer is "[tex]12 * 16 = 20^2[/tex], therefore the triangle is a [tex]right[/tex] [tex]triangle[/tex]"

This is known as the Pythagorean Theorem, meaning that [tex]a^2+b^2=c^2[/tex], with [tex]a[/tex] and [tex]b[/tex] being the length of the shorter of the three sides, and [tex]c[/tex] being the length of the hypotenuse, or the length of the longer of the three sides.

Have a super awesome day! :)

Answer:36

Step-by-step explanation:

[tex]\frac{4}{7} =\frac{48\\}{84}[/tex]

for every 7 students there are 4 girls, so for every 84 there must be 48

7*12=84

4*12=48

so, in all 84 students there are 48 girls

so amount of boys=84-48=36

there are 36 boys

2. 25%

3. 350%

4. 125%

5. 30%

6. 45%

7. 59%

8. 380%

Step-by-step explanation:

to find the precentage of a fraction u have to try and make the bottom number 100, 1000, 10000 etc

to do that like the first 1 u do 2 x ? = 100 the answer is 50

Rule what u do to the bottom u have to do to the top

now that u multiply 50 down to make 100 u have to do as the rule say what u need to do is also multiply 1 to 50 to get the answer

as u might know that 100 mean % so u pet the top number and then %

Answer:

12 in

Step-by-step explanation:

Use Pythagorean theorem

Cost of a television Ms. Singh wants to buy = £840

Ms. Singh's weekly wage = £300

Money she saves each week :

= 40% of her weekly wage

[tex] =\tt 40\% \: of \: 300[/tex]

[tex] = \tt \frac{40}{100} \times 300 [/tex]

[tex] =\tt \frac{40 \times 300}{100} [/tex]

[tex] =\tt \frac{12000}{100} [/tex]

[tex]\color{plum} = \tt£120[/tex]

Thus, Ms. Singh's weekly savings = £120

Number of weeks in which she will be able to buy a TV :

[tex] = \tt \frac{840}{120} [/tex]

[tex]\color{plum} =\tt 7 \: weeks[/tex]

Therefore, Ms. Singh will be able to buy a TV from her savings in 7 weeks.

Hi!! I'd love to help!!

The slope of your points is 2.

When we use the slope intercept formula (y=mx+b), we get y=2x-2.

So the answer to your question is C

Step-by-step explanation:

for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.

For AB

A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.

For BA

B has 2 columns and A has 2 rows it also matches so can be multiplied

You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:

c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.
