2 times the length of the midsegment equals the length of the base. That being said, your equation will be 2(x+21)=x+32.
First, use the distributive property on 2(x+21). You are left with 2x+42=x+32.
Subtract x from both sides. You are left with x+42=32.
Finally, subtract 42 from both sides of the equation. You are left with your answer: x=-10.
Check your work: -10+21=11 and -10+32=22
11 is half of 22.
The linear velocity of the clock hand is 0.200 cm per minute.
Answer:
b. x^2+4x
Step-by-step explanation:
So since you don't know the width, you can just represent it as a variable, and in this case that variable will be "x". Now using this variable we can use it to represent the length since there is a relationship between the width and length which is given. Since the length is 4 feet greater than the width, we can represent the length as (x+4). Now to find the area, we simply multiply the length * width, which is x * (x+4) = x^2 + 4x
