Answer:
6 and -14
Step-by-step explanation:
Area of the triangle = 1/2 ab
42 = 1/2 (x)(x+8)
42 *2 = x(x+8)
84 = x²+8x
x²+8x-84 = 0
x²+14x-6x-84 = 0
x(x+14)-6(x+14) = 0
x-6 = 0 and x+14 = 0
x = 6 and -14
Hence the values of x are 6 and -14
Answer: 3.62 inches
Step-by-step explanation:
Diego's cousin is too short for this ride, we know how tall he is now and what height he needs to be.
This can be solved by subtracting his needed height from his current height.
39.37-35.75=3.62 inches
The solution to the system of equation is D
