Answer:
12 (or A)
Step-by-step explanation:
A coefficient is the number before a variable.
Examples: 5r , 34y, 10x^2 (the coefficients are 5, 34, and 10)
12 has a variable after it, so 12 is a coefficient.
-8 - 7x is the factored version.
Answer:
D
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos66° = = ( multiply both sides by x )
x × cos66° = 13 ( divide both sides by cos66° )
x = ≈ 32.0 ( to the nearest tenth )
Answer:
-3
Step-by-step explanation:
f(x)= x²+3x-1
f(-1)= (-1)²+3(-1)-1
= 1-3-1
= -2-1
= -3
Answer:
240
Step-by-step explanation:
360 divided by 3 is 120 so 2 times 120 is 240
