Answer:
10) 51°
11) 152
Step-by-step explanation:
10) 42 + 9 = 51
11) 45(3.5) + 22(-.25) = 157.5 - 5.5 = 152
Answer:
-x^3-5x^2+10x-4
Step-by-step explanation:
(−x + 1) (x ^ 2 + 6x − 4) = (-x)(x ^ 2 + 6x − 4) + 1(x ^ 2 + 6x − 4)
= -x^3-6x^2+4x+x^2+6x-4 = -x^3-5x^2+10x-4

Let's start by writing out their factors.
4: <em><u>1</u></em><em>, </em><em><u>2</u></em><em>, </em><em><u>4</u></em>
24: <em><u>1</u></em><em>, </em><em><u>2</u></em><em>, 3, </em><em><u>4</u></em><em>, 6, 8, 12, 24</em>
The greatest factor that
and
have in common is
.
Factor out
from both terms. 
2.25 is 2 1/4 because there are 25 centrs in a dollar so 4*25 = 100.
<u>Answer:</u>
f(x) = 7 is an even function.
<u>Step-by-step explanation:</u>
Any function is even when
and gives a graph that is symmetric with respect to the y-axis.
We are given these options and we have to check whether which of them is an even function:

and
- This function is not even

and
- This function is not even

and
- This function is not even

and
- EVEN FUNCTION
We get the same value for
and
, therefore f(x) = 7 is an even function.
