Answer:
The triangle should be 16 inches wide.
Step-by-step explanation:
What we know:
- One of the legs measures 12 inches.
- The hypotenuse is 20 inches.
We need to solve for b. Solving for a while b is 12 would also be acceptable.
We will use the first equation.
The triangle should be 16 inches wide.

Step-by-step explanation:
The <em><u>correct answers</u></em> are:
3/2 - expansion; 1/4 - contraction; 4 - expansion; 0.8 - contraction; -3 - expansion.
Explanation:
A scale factor larger than 1 would be an expansion. The factors we have listed that are larger than 1 are 3/2 and 4.
A scale factor between 0 and 1 would be a contraction. The factors we have listed that are between 0 and 1 are 0.8 and 1/4.
A negative scale factor will result in a larger, inverted figure. This means the scale factor of -3 will be an expansion.
Part A: make slope-intercept form of equation
We will have variable y for the depth of the submarine after x hours. The start 1,500 will be written -1,500 because it's below surface of water.
The equation after x hours will be
y = -1,500 + 52x
y = 52x - 1,500
Part B: Find the depth after two hours
Change variable x with 2
y = 52x - 1,500
y = 52(2) - 1,500
y = 104 - 1,500
y = -1,396
Negative means it's below surface
