20% of 30
Or .20×30 and you'll get your answer
Answer:
Step-by-step explanation:
Small number = x - 14
Large number = x
x + x - 14 = 56
2x = 70
x = 35
Small number = 35 - 14 = 21
Large number = 35
The formula for the area of a triangle is (base × height)/2. We know that the height is 9, so we can reverse the formula:
(base × 9)/2 = 54
× 2
base × 9 = 108
÷ 9
base = 12
So your answer is 12m. I hope this helps!
After distribution, you should have x to the second power plus 2x
x^2 +2x
