Answer:
it is 7
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
To evaluate the expression, we have to substitute the variable in the expression, z, for its stated value. Given that z = 6, substitute 6 for the z in the expression and solve:

Thus, the answer is 3.
Base= x
Height= 4+x
Area = (1/2)(x)(4+x) = 6
Hence, quadratic equation is,
(x)(8+2x) = 12
