2f(x) + 4 = 2(3x + 4) +4

Use the property
a(b+c) = ab + ac

2(3x+4) +4 = 2(3x) + 2(4) + 4
= 6x + 8 + 4
= 6x+ 12

Can anyone Explain in words why these are equivalent expressions.
N76 [4]

Answer:

The distributive property says that when there is a number outside of parenthesis, this means it should be distributed (or multiplied) to the values inside the parenthesis.

So in this situation, 10 x b = 10b

and 10 x 4c = 40 c

so 10(b + 4c) becomes 10b + 40c once the 10 is distributed within the parenthesis.

I hope this helps!

In the rectangle below,
STALIN [3.7K]

Answer:

Step-by-step explanation:

In a rectangle,  diagonals are equal and bisect each other

BE  =   AE

6x - 5 = 2x +  7

6x - 2x - 5 = 7

       4x - 5 = 7

             4x = 7 + 5

             4x = 12

               x = 12/4

               x = 3

AE = 2x + 7

     = 2*3 + 7

    = 6 + 7

AE =  13

AC = 13 + 13

AC = 26

m∠EBC = 50

In rectangle, each angle is 90

m∠ABE + m∠EBC = 90

m∠ABE + 50 = 90

          m∠ABE = 90 - 50

          m∠ABE = 40

In rectangle, AB // DC and DB transversal

m∠ECD = m∠ABE   { alternate interior angles}

m∠ECD = 40

The movie theater add 352 people in it.if the people split into eight even groups to watch different movies how many people Will
Dovator [93]
The answer is 44 because the equation is 352 divided 8. And 8 goes into 352 44 times. If you want to check the work you can also multiply 44 and 8, and it should be 352.

So the answer is 44
Hope this Helps:)
