Answer:
b
Step-by-step explanation:
area of triangle = 1/2 x c x d =cd/2
area of semicircle = 1/2 x π x r^2 = 1/2 x π x (a/2)^2 = 1/2 x π x a^2/4 =πa^2/8
area of shape = area of triangle + area of semicircle
First you need to find out what times 4 equals 8. You should know that it is 2 because 2×4=8. Then it should look like this
![8 \sqrt{8}](https://tex.z-dn.net/?f=8%20%5Csqrt%7B8%7D%20)
and that should be your answer or what ever your problem says to do.
Hope this helped :)
Answer:
Width = (x-2)
Step-by-step explanation:
The area of a rug is given by ![(x^2+4x-12)](https://tex.z-dn.net/?f=%28x%5E2%2B4x-12%29)
The length of the rug is (x+6)
We need to find the width of the rug.
The area of a rug is given by :
![A=lb\\\\x^2+4x-12=(x+6)b\\\\b=\dfrac{x^2+4x-12}{(x+6)}\\\\b=\dfrac{x^2+6x-2x-12}{(x+6)}\\\\b=\dfrac{x(x+6)-2(x+6)}{(x+6)}\\\\b=\dfrac{(x+6)(x-2)}{(x+6)}\\\\b=(x-2)](https://tex.z-dn.net/?f=A%3Dlb%5C%5C%5C%5Cx%5E2%2B4x-12%3D%28x%2B6%29b%5C%5C%5C%5Cb%3D%5Cdfrac%7Bx%5E2%2B4x-12%7D%7B%28x%2B6%29%7D%5C%5C%5C%5Cb%3D%5Cdfrac%7Bx%5E2%2B6x-2x-12%7D%7B%28x%2B6%29%7D%5C%5C%5C%5Cb%3D%5Cdfrac%7Bx%28x%2B6%29-2%28x%2B6%29%7D%7B%28x%2B6%29%7D%5C%5C%5C%5Cb%3D%5Cdfrac%7B%28x%2B6%29%28x-2%29%7D%7B%28x%2B6%29%7D%5C%5C%5C%5Cb%3D%28x-2%29)
So, the width of the rug is (x-2). Hence, the correct option is (c).
B. They intersect at one point
Answer: 450
Step-by-step explanation:
You will do 50 times 9, and then you will get 450. You get this answer because you get 50 each day so you will need to multiply 50 times 9 to figure out how much she earns on the ninth day.
