Answer:
x² + 5x + 6
Step-by-step explanation:
Foil means first, outside, inside, last
First: (x+2)(x+3)
x × x = x²
Inside: (x+2)(x+3)
x × 3 = 3x
Ouside: (x+2)(x+3)
2 × x = 2x
Last: (x+2)(x+3)
2 × 3 = 6
adding them together:
x² + 3x + 2x + 6 = x² + 5x + 6

Answer:
The answer is B
Step-by-step explanation:
Because 3 1/5 as a decimal is 3.2
So 3.2 x 7 = 22.4
converted to a fraction is 11 2/5
and 22 2/5 simplified is 11 2/5
Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y =
( multiply both sides by x³ )
x³y = 19 ( divide both sides by y )
x³ =
( take the cube root of both sides )
x = ![\sqrt[3]{\frac{19}{y} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B19%7D%7By%7D%20%7D)
Change y back into terms of x, then
(x) =
=
→ A
