Answer:
x = 13 1/2
Step-by-step explanation:
16x -12x+0=54
combine like terms
4x + 0 = 54
4x = 54
divide each side by 4
4x/4 = 54 /4
x = 54/4
x = 13 2/4
x = 13 1/2
Answer:
5
Step-by-step explanation:
Answer:
81y^4 - 16x^2, difference of squares.
Step-by-step explanation:
So we need to expand the following product:
(9y2-4x)(9y2+4x) = 9y2*9y2 + 4x*9y2 - 4x*9y2 -4x*4x = 81y^4 - 16x^2
And this type of product is the difference of squares.

Step-by-step explanation:
<u>Step 1: Define</u>
g(x) = 4x + 4
g(4) is x = 4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: g(4) = 4(4) + 4
- Multiply: g(4) = 16 + 4
- Add: g(4) = 20
