GREYUIT [131]2 years ago
3 0

Answer:

12a^5+15a^3b^2-24b^3a^2-30b^5

Step-by-step explanation:

(3a³-6b³) (4a² + 5b²) -> <u>Simplify</u> not Multiply

Expand (3a³-6b³) (4a² + 5b²) using the FOIL Method.

Apply the <u>distributive property</u>.

3a^3(4a^2+5b^2)-6b^3(4a^2+5b^2)

3a^3(4a^2)+3a^3(5b^2)-6b^3(4a^2+5b^2)

3a^3(4a^2)+3a^3(5b^2)-6b^3(4a^2)-6b^3(5b^2)

<h3><u /></h3>

<u>Simplify each term.</u>

Rewrite using the <u>commutative property of multiplication</u>.

3*4a^3a^2+3a^3(5b^2)-6b^3(4a^2)-6b^3(5b^2)

↓

12a^5+15a^3b^2-24b^3a^2-30b^5

<em />

<em>Equation Simplified.</em>

Julian calculates the volume of a rectangular prism with the dimensions 3/4ft by 4 feet by 1/2 ft. His work is shown here.
lbvjy [14]

Answer:

He multiplied the denominators incorrectly

Step-by-step explanation:

we know that

The volume of a rectangular prism is given by the formula

V=LWH

we have

L=3/4 ft

W=5/1 ft

H=1/2

substitute

V=(3/4)(5/1)(1/2)= 3x5x1=    15

                           ₋₋₋₋₋₋₋₋    ₋₋₋₋ ft³

                           4x1x2=    8

                       

therefore

He multiplied the denominators incorrectly

How does the order of operations relate to solving multi-step equations? Use examples of solving an equation, and then evaluatin
givi [52]
The order of operations helps keep answers for multi-step equations similar. If the proper order of operations are not followed, then answers may vary. To show an example:

4 / 2 - 1

The proper order of operations would be:

Divide first, before subtracting
4 / 2 - 1
2 - 1
1

But if subtracting was done before dividing:

4 / 2 - 1
4 / 1
4

So not following the proper order would yield different and erroneous answers.
