Answer:
-4x^2+5x-28
Step-by-step explanation:
Expand -7(x^2 +4) = 3x^2+5x-7x^2-28
Simplify 3x^2+5x-7x^2-28 = -4x^2+5x-28
Answer:
d
Step-by-step explanation:
cosA^2 = 1 - sinA^2
subtitute 1/4 below
= 1 - (1/4)^2
= 1 - 1/16
after calculation
= - 0.9682
The first step to solve this is to multiply the numbers
42 + 312 - 33 ÷ 32
then divide the numbers
42 + 312 - 1.03125
use the addition and subtraction rules to calculate the expression
352.96875
this means that the correct answer to your question will be 352.96875.
