How do you know that (-3/4) (-8a) + (-3/4) (-12) is equivalent to both -3/4(-8a - 12) and 6a + 9?
Answers
Answer:
Step-by-step explanation:
We know these outcomes by applying Order of Operations rules.
(-3/4) (-8a) + (-3/4) (-12) after performing the two indicated multiplications is
6a + 9.
The original (-3/4) (-8a) + (-3/4) (-12) can be factored as follows:
(-3/4) (-8a) + (-3/4) (-8a - 12) = (-3/4)(-8a - 12)
Answer:
,
Step-by-step explanation:
[tex]\frac{-3}{4}*(-8a) + (\frac{-3}{4})* (-12) = (-3)*(-2a) + (-3) * 3\\ = 6a + 9[/tex]
Here, we simplified the expression.
[tex]\frac{-3}{4}*(-8a) + (\frac{-3}{4})(-12) = (\frac{-3}{4})(-8a - 12)[/tex]
Here, (-3/4), the common factor for two terms is taken outside.
On their farm, Beth’s parents decided to plant beans in a certain area. They chose an area that was 1/2 of an acre wide and 3/4 of an acre long. Choose the model that shows the area they’ll use for beans.
options:
3/4
6/8
4/10
3/8
Answers
Answer: The answer is 3/8
Step-by-step explanation: For this problem you only need to multiply the fractions. So when you multiply the two fractions you first multiply both numerators so 1 X 3 = 3 then the denominators 4 X 2 = 8. So the fraction is 3 over 8 3/8.

you subtract 80 from 180 to get the sum of y and 60, which is 100. because y doesn’t include the 60 degrees, you subtract 60 from 100.
then, you get 40 for y. because x is a vertical angle of y, you get 40 for x as well since they’re congruent to each other.
Answer:
40°
Step-by-step explanation:
So a straight line is 180°...
(Supplementary angle) You have 80+60=140
180-140=40°
Y= 40°
Y is equal to x since it is the alternative angle

What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given a square pyramid,
The base side is 2 inches and height is 5 inches.
We need to find surface area of pyramid=
=area of square+4(area of straingle)
=(S²)+4(1/2bh)
Where s is side length of base.
b is base of triangle which is 2 inches.
h is the height of triangle = 5 inches
Substitute these in the formula
=2²+4(1/2×5×2)
=4+(20)
=24 square inches.
Hence 24 square inches of cardboard make up this square pyramid

If your scores on your Math Tests for this quarter are 10, 7, 8, 7, 9, 6, 7, 10, What is the MEAN, MEDIAN and MODE for the 3rd quarter? Make sure to show your work and to list the numbers from LEAST to GREATEST.
Pls help I am so bad at this :’)
Answers
Answer:
Step-by-step explanation:
The first thing you need to do is order the numbers from least to greatest.
This would be:
6, 7, 7, 7, 8, 9, 10, 10
To find the Mean, add up all of your numbers and then divide by how many numbers there are altogether. In other words, it is the sum divided by the count.
In this case, it would be:
6+7+7+7+8+9+10+10
= 64, your MEAN
To find Median, you basically need the middle number.
For example:
a, b, c, d, e
c would be your Median because it is in the middle.
Other cases like if you had an only 4 letters or numbers you would have to divide it.
For example:
1, 2, 3, 4
The median would be 2 and 3. BUUUTTT because you can only have 1, you have to do 2.5, since 2.5 is the number inbetwen 2 and 3.
To find Mode, you basicly
see what number appears more.
In your case it would be 7. It appears 3 times compared to the 1 and two times the other numbers appear.
Hope that helps!! :)

Mr. Alter found a t-shirt at Kohl’s for a ticketed price of $24. He had a coupon for 20% off. The sales tax rate was 8%. How much did the t-shirt cost? Please round your answer to the nearest cent. p
Answers
to find the answer you multiple $24 by 20% and you get 4.8. once you’ve done that you subtract 4.8 from 24 which gives you 19.2. Then do the same thing but with 8% so multiple 19.2 by 8% and you get 1.536. Finally subtract 1.536 from 19.2 and you end up with 17.664 round it and you get $17.66.

The sum of the three interior angles of a triangle is 180 degrees.
A- 3 a = 180°
B- a + 55° + 36° = 180°
C- x + y + z = 180°
D- x3 = 180°
E- x · y · z = 180°
Answers
Answer:
A) 3a = 180°
B) a+ 55° + 36° = 180°
C) x + y + z = 180°
Step-by-step explanation:
The answer is the A option since all the side of the triangle could be the same, making it an equilateral triangle. ( 60° + 60° + 60° = 180° )
The sum means that all the angles are added, not necessarily being similar terms, which equals to 180°.
The terms don't have to be similar, for instance the B option,
a+ 55° + 36° = 180°
since you could find the value of a.
The same thing goes for C.
(Extra)
It is not D since x is multiplied with 3, not giving the sum.
It is not E since all the 3 terms are multiplied, not giving the sum.

Answer:
A
Step-by-step explanation:
to find the area of a circle you need to multiply the radius by pie (3.14)
56.52 ÷ 3.14 = 18
18 ÷ 2 = 9
9 ⋅ 3.14 = 28.26

A. (x2−4x)
B. (x−2)
C. (x2−2)
D. (x2−4)
Answers
Answer:
B. (x−2)
Step-by-step explanation:
Factor out x^2
x^2(x+2)-4x-8
Factor out 4
x^2(x+2)-4(x+2)
Now combine
(x^2-4)(x+2)
Factor x^2-4 (notice that it is a difference of squares)
(x+2)(x-2)(x+2) -x+2 is twice so we can square it
(x+2)^2(x-2)
