Answer: x = 6
Step-by-step explanation:
Solve for x in the equation.
-2x + 12 = 0 subtract 12 from both sides
- 12 -12
-2x = -12 Divide both sides by -2
x = 6
Now input 6 into the equation for x and check if it is true.
-2(6) + 12 = 0
-12 + 12 = 0
0 = 0
x is indeed 6.
Answer:
A = 24 m^2
The unit is m^2
Step-by-step explanation:
The area of the rectangle is found by using the formula
A = l*w
where l is the length and w = width
A = 3m * 8 m
A = 24 m^2
The unit is m^2

Answer:
62 degrees
Step-by-step explanation:
If two angles are complementary, it means that their sum is 90degrees
Hence if m<a and m<b are complementary, then;
m<a + m<b = 90
Given
m<a = 28degrees
Required
m<b
Substitute into the formula as shown;
28 + m<b = 90
m<b = 90 - 28
m<b = 62degrees
Hence the measure of angle b is 62 degrees
