Answer:
See explanation!
Step-by-step explanation:
<u>Due to the way the question is expressed we will assume that it means to find the product of this expression (thus simplify or factor our the equation). </u>
So let us solve as following:

So we have factored our the expression and solve for the values of
which since its <em>squared, </em>the solution can be either positive or negative. Thus
and 
X+10=3x-4
14=2x
x=7
This is just for the 20 chars
Answer:
x = 8
Step-by-step explanation:
Here, we want to find the value of x
According to the theorem;
45 = 1/2(147 - (7x-5))
90 = 147 -7x + 5
90 = -7x + 147
7x = 147-90
7x = 57
x = 57/7
x = 8.142 which is approximately 8
So the image consists of 1 rectangle and half a circle.
Rectangle - 12*19 = 228
Half a circle -

In the end there are 2 rectangles (2*228 = 456) and 1 full circle (18*2 = 36), which makes the shaded area 456 ft and 36
