A. The water will go down 2 inches
B. The water will go down 4.5 inches
C Half of the question is missing.
For the first question the answer is
X=-9 or X=10
First you factor the left side of the question
(X+9)(X-10)=0 then u set factors equal to zero
X+9=0 or x -10=0
X=-9 or X=10
Now for question two is the second bubble of answer
The scale factor that Thea uses to go from Rectangle Q to Rectangle R is equal to 6.
<h3>What is the scale factor from rectangle Q to rectangle R?</h3>
In geometry, the scale factor is a ratio of the resulting length to the initial length. Since the area of the square is equal to the square of its side length, then the scale factor is equal to:
k² = A' / A
k = √(A' / A)
Where:
- k - Scale factor
- A' - Area of the rectangle R.
- A - Area of the rectangle Q.
If we know that A = 2 and A' = 72, then the scale factor is:
k = √(72 / 2)
k = √36
k = 6
Then, the scale factor that Thea uses to go from Rectangle Q to Rectangle R is equal to 6.
