2z + 8 = −6
2z + 8 -8 = -6 -8 ( add - 8 for both sides)
2z = -14
2z/2 = -14/2 (divide both sides by 2)
z = - 7
So the answer is -7


3 x 7 = 21
10 x 4 = 40
10 x 7 = 70



So, the number that belongs in the green box is 19.

Answer: 22 square feet
Step-by-step explanation:
Using Heon's formula, the are can be found with:

Where s is half the perimeter
a, b and c are sides
Perimeter = a + b +c
24 = 9 + 10 + c
c = 24 - 9 - 10
c = 5 feet
s = 24 / 2 = 12
Area

= 22 ft²
