Mark was making a ramp for handicapped people. The board he used was 26 feet long. From the bottom of the curb to the bottom of the ramp was 24 feet. How tall is ramp suppose to be?
A^2 + B^2 = C^2
A^2 + 24^2 = 26^2
A^2 + 576 = 676
A^2 + 576 - 576 = 676 - 576
A^2 + 0 = 100
100 square rooted = 10
The Ramp is 10 feet tall.
( I think I made the ramp too tall)
A^2 + B^2 = C^2
A^2 + 24^2 = 26^2
A^2 + 576 = 676
A^2 + 576 - 576 = 676 - 576
A^2 + 0 = 100
100 square rooted = 10
The Ramp is 10 feet tall.

Answer:
2x² +5x -12 = 0
Step-by-step explanation:
When p and q are roots of a quadratic, its factored form can be written as ...
(x -p)(x -q) = 0
Here, the roots are given as -4 and 3/2, so the factored form would be ...
(x -(-4))(x -(3/2) = 0
Multiplying by 2 gives us ...
(x +4)(2x -3) = 0
Expanding the product, we find the desired quadratic is ...
2x² +5x -12 = 0
