Answer:

A: 5

B: 6

C: 3x^2 - 2x

D: 8

E: 22

Step-by-step explanation:

A: (-1)^2 + 4 = 5

B: (-4)^2 +4 = 16

2 x (-3) -4 = -10,

16-10=6

C: 3(x^2 + 4) = 3x^2 + 12

3x^2 + 12 -2x -4, simplify

3x^2 - 2x

D: g(3) = 2*3 -4 = 2

f(2) = 2^2 +4 = 8

E: f(3) = 3^2 + 4 = 13

g(13) = 2*13 - 4 = 22

when you divide a whole number by a fraction with a numerator of 1, explain how you can find the quotient

Something like 4//1/255 ?
just multiply The number you started with be the denominator of the fraction.

4 * 255 = 1020

The reason why is that though I didn't say so you are actually multiply both top and bottom by 255

4 * 255
==
1 * 255
--
255
The bottom 255s cancel. and you are left with 4 * 255 on the top.
Short cut you want. Short cut you get.
