4a-8=28
add 8 to both sides to start to isolate the variable (a)
-8+8 cancels each other out
28+8=36
4a=36
to completely isolate the variable divide both sides by 4
4a÷4=a
36÷4=9
a=9

Varvara68 [4.7K]

Answer:

Let Hassan score be X

Then Dionnie score will be  X + 4

: the sum of Hassan and Dionnie is 180

X + ( X + 4 ) = 180

X + X + 4 = 180

COLLECTING LIKE TERMS

2X = 180 – 4

2X = 176

A. (x+2) (x2 +x+2) + 2(x3 + x2)
hram777 [196]

Answer:

3x³ + 5x² + 4x + 4

Step-by-step explanation:

Given

(x + 2)(x² + x + 2) + 2(x³ + x²)

To expand the product, each term in the second factor is multiplied by each term in the first factor, that is

x(x² + x + 2) + 2(x² + x + 2) + 2(x³ + x²) ← distribute the parenthesis

= x³ + x² + 2x + 2x² + 2x + 4 + 2x³ + 2x² ← collect like terms

= 3x³ + 5x² + 4x + 4
