Answer:
16 cm2
Step-by-step explanation:
By equa tion of area of triangle: S = 1/2 * height * base
Triangle B: 32 = 1/2 * 8 * x --> x = 8 (cm)
The base of triangle A is half of the base of triangle B so it is 4 cm.
The area of triangle A = 1/2 * 8 * 4 = 16 (cm2)
-x = 4 -3x + 6
First, let's get x on one side.
Add 3x to both sides.
-x + 3x = 2x
-3x + 3x = 0
We now have:
2x = 4 + 6
Combine like-terms (add 4 to 6)
4 + 6 + 10
2x = 10
Divide both sides by 2 to solve for x.
2x / 2 = x
10 / 2 = 5
We're now left with:
x = 5

Don’t know the answer to the question but I don’t know the answer question mark I don’t know what about it I don’t I don’t know I just really don’t know I don’t know the answer would help you but I don’t know
The answer is 168. 12% is also 0.12. 150(0.12) is 18. 150+18=168
