Answer:
-10
Step-by-step explanation:
-5(2) - 4(-1) - 8 +2(2)
Answer:
a + 20 = 7*12 (multiplied both sides by 12)
a + 20 = 84 (calculated 7*12)
a = 84 - 20 (subtracted 20 on both sides)
a = 64 (calculated 84-20)
The surface area of a shape is the amount of space on the shape
When the dimensions are quadrupled, the new surface area would be 16 times the initial surface area
<h3>How to determine the surface area</h3>
The surface area of a rectangular prism is:

When quadrupled, we have:

Factor out 16

Substitute 

The above means that:
The new surface area would be 16 times the initial surface area

Answer:
Hi it's down below! Hope it helps
Step-by-step explanation:
1) The angles are Supplementary
This is because both angles form 180°. The angle below angle "7x+9" is the same as 5x+3. The angle above angle"5x+3" is the same as 7x+9.
2) They are both supplementary
They form 180°
3)180° = 12x+12°
4) Solving that:
180° - 12° = 12x
168° = 12x
x = 168°/12
x = 14°
