If you're looking for the value of z, then the answer should be -5.
Answer:
[-2, ∞]
Step-by-step explanation:
15 - √(x+2)
domain is any value as long as (x+2) is not-negative, since √ of a negative number has no Real solution.
x+2 ≥ 0 ⇒ x ≥ -2
Area is base multiplied by height, so to get the answer you'd need to multiply 6.5 and 4
