I will do a and b and you do the rest.
For (a), the equation is x + y = 154.
For (b), the equation is 320x + 85y = 14,970.
We have two equations in two unknowns.
Use the substitute method to find x and y (the given c). Once you have x and y, use that to find d.
Take it from here.

The area of the parallelogram is 36 inches square.
We have a parallelogram shaped window whose dimensions are as follows-
base (b) : 12 inches
height (h) :
= 6 inches
Other side = 10 inches
We have to find the area of the window.
<h3>What is the formula to calculate the area of a parallelogram of given base (b) and height (h).</h3>
The area of the parallelogram is given by -

In the question given - We can apply the above formula to estimate the area of the window.
A =
= 36 inches square.
Hence, the area of the parallelogram is 36 inches square.

Answer:
4a +4
Step-by-step explanation:
The average rate of change of f(x) on the interval is ...
(f(a) -f(1))/(a -1)
= ((4a² -6) -(4(1)² -6))/(a -1) = (4a² -4)/(a -1)
= 4(a² -1)/(a -1) = 4(a +1) = 4a +4
The average rate of change on the interval is 4a +4.
