I'm assuming the original expression is 6(A+2)+5A

If so, then,

6(A+2) + 5A
6*A+6*2 + 5A ... distribute
6A + 12 + 5A ... multiply
6A + 5A + 12 ... commutative property
11A + 12 ... combine like terms

The original expression simplifies to 11A+12

Answer:

The simplified form is

6(A+2)+5A=11A+12

Step-by-step explanation:

Given the expression

6(A+2)+5A

we have to simplify the above expression

The expression is

6(A+2) + 5A

Using distributive property, a.(b+c)=a.b+a.c

(6.A+6\times 2) + 5A

(6A + 12) + 5A

By associative property of addition a+(b+c)=(a=b)+c

6A+(12+5A)

Using commutative property i.e a+b=b+a

(6A + 5A) + 12

Combining like terms, we get

11A+12

which is required simplification

Find the volume of a rectangular prism with the width of x-1, a length of x+1 and a height of 2x-3.
Damm [24]

Answer:

The Volume is equal to 2x^3-3x^2+2x-3

Step-by-step explanation:

Formula for the volume of a rectangular prism is V=WHL

We know that:

W=x-1

L=x+1

H=2x-3

So, V= (x-1)(x-1)(2x-3)

Simplify

(x^2+1)(2x-3)

2x^3-3x^2+2x-3

Anna does sit-ups to get ready for her first triathlon. When she starts, she does a sit-up every 222 seconds. But, as she gets t
Alexeev081 [22]

Answer:

Choice B) No.

Step-by-step explanation:

When she starts , she does a sit-up every 222 seconds.

But as she gets tired, each sit-up takes longer and longer to do.

It means, each sit-up takes more time than she did at beginning.

So, it is NOT proportional to the time.

If it is proportional, she should take constant number of sit-ups even she get tired.

Work out the value of a and b in the identity.<br> 3ax + 6 - 4(x + b)= 11x + 14
Levart [38]

Answer:

a=5, b=-2

Step-by-step explanation:

If you simplify the equation, you get:

3ax +6 -4x -4b - 11x - 14 = 0 =>

3ax - 15x -4b -8 = 0

group together x's and constants:

(3a-15)x -8 -4b = 0

To make this 0 for all x, we have to find an a such that 3a-15 = 0 and b such that -8-4b = 0. this leads to a=5, b=-2
