Answer:
12
Step-by-step explanation:
if R = 9
9-8=1
9 + 3 = 12
12*1=12
Given function :
.
We need to find the values of f(-2).
In order to find the value of f(-2), we need to plug x=-2 in the given fucntion
.
Replacing x by -2, we get

We get (-2)^2 = -2 *-2*-2=-8 and (-2)^2 = -2 * -2 = 4.
.

f(-2) = -160 +12.
f(-2) = -148.
Therefore, correct option would be option D. That is f(-2)=-148.
Answer:
83 degree because it is 180-97

Answer: x = 30' , y = 45'
hope this helps
Step-by-step explanation:
U is 90' it's a right triangle
well simple VRT you already know 2 angles which is 60' and 90'
R = 60'
V = 90'
T = x
you know that a triangle = 180'
so you do
180 - 60 - 90 = x
30 = x
if you want to do y
then you already know that U is 90' on both sides.
since you also know S,
S = 45'
U = 90'
V = y
180 - 90 - 45 = y
45 = y
