Answer:
Step-by-step explanation:
The area of a rectangle can be found with the formula 
, where 
is the length of the rectangle and 
is the width.
From the given problem statement, we know that 
and 
, so we can fill in those values in the formula anbd solve for to get the width:
Divide both sides by 
to isolate by itself:
Answer:
It's C
Step-by-step explanation:
Because the angle measurements are the same on rectangles and they have the same side lengths but the one on the right is a smaller rectangle which its only half the side of the bigger one.
You will need three roots for this, so we have
Let x = -30, -10 and +20
So the factors will be (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 * (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)
Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
Answer:
1/4 of the answer
Step-by-step explanation:
Answer:
$20
Step-by-step explanation:
<em>20% is equal to 20/100 therefore, if 5 x 20 is 100, you would multiply 5 x 4 and get 20, </em>
the reason you don't subtract the $4 is because it says "was" so the answer is $20
