Answer:
Perimeter ratio: 11:6
Area ratio: 121:36
Step-by-step explanation:
The ratio of length of the perimeter of one similar figure to another is the ratio of the side lengths.
The ratio of the areas is the ratio of the squares of the side lengths.
A = ((B+b)*h)/2
A = ((6+4)*3)/2
A = 15
Step-by-step explanation:
3(x+2)-(2x-1)=4(3-x)
3x+6-2x+1=12-4x
3x-2x+4x=12-6-1
5x=5
x=1
Answer:
A. 48r² - 10r + 3
Step-by-step explanation:
Solve (6r - 1) × (-8r - 3)
1. <u>Distribute 6r and -1</u> (into -8r - 3):
-48r² - 18r + 8r + 3
2. <u>Combine like terms</u> (-18r and 8r):
-48r² - 10r + 3
So, your answer is -48r² - 10r + 3
