Answer:
22
Step-by-step explanation:
Find f(-3) :
f(x) = x² + 2x for x ≤ -3
That means for those values of x, less than or equal to -3, this is the function.
So, f(-3) = (-3)² + 2(-3) = 9 - 6 = 3
Now, f(-1) :
From the given data, we see it is: f(x) = 2 
We take this because -1 lies between -3 and 4.
Now, f(-1) = 2 
=> 
For f(4) :
Clearly, the function is: 
Therefore, <u>f(-3) + f(-1) - f(4) = 3 + 18 - (-1) = 3 + 18 + 1 = 22.</u>
Side a can be broken into to rectangles having areas:
(12-8)*4 and 8*12 so the area of side A is
A=16+96
A=112cm^2
Answer:
b<negative 4/7
Step-by-step explanation:
negative 4/7 plus5/7= 2/7
so b has to be less than negative 4/7.

4% means <span>4100</span> 'of' means multiply so:
<span>363.99⋅<span>4100</span></span> is <span>363.99⋅4</span> = 1455.96
<span>1455.96100</span> = 14.56 (rounded up)
<span>363.99+14.56=$378.55</span> to the nearest cent.
