-3 + 2x = 11
Add 3 to both sides.
2x = 14
Divide by 2.
x = 7
We can model the problem as a rectangle triangle.
We know two sides.
We want to find the hypotenuse.
Using the Pythagorean theorem we have:
h = root ((8) ^ 2 + (3.9) ^ 2)
h = 8.9 feet
Answer:
this statement is true:
The length of the ramp is 8.9 feet
5
3r - 14 that would be the answer
The problem is you can’t simplify 3/7
