Answer:
The length is 15 and the width is 10
Step-by-step explanation:
Let l = length
w = l-5
We know the area is 150
A = l*w
150 = l ( l-5)
150 = l^2 - 5l
Subtract 150 from each side
0 = l^2 - 5l - 150
Factor
0= ( l+10) ( l-15)
Using the zero product property
l+10 =0 l-15=0
l = -10 l = 15
Since we cannot have a negative length
l = 15
w = 15-5 = 10
The length is 15 and the width is 10
Use Pythagorean theorem.
15^2+20^2=c^2
225+400=c^2
√655=c
c=25

Answer:
F (x, y) ----> (x, y - 7)
Step-by-step explanation:
The triangles have the same dimensions. The second triangle is a translation of the first one. It was translated 7 units down, so every y-coordinate value became 7 less than what it was. It did not move left or right, so the x-coordinates remain the same.
Answer: F (x, y) ----> (x, y - 7)
