Answer:
B) 9π in^2
Step-by-step explanation:
Circumference of a circle is C = πD
Divide 6π by π to get 6 then divide by 2 to get the radius of the circle
Area of a circle is A = πr^2
6/2 = 3 3 = r
π(3)^2 = 9π
Its B.6 because when you plug in 1 for y the equation is 3x-1=17 and you have to cancel out y to get 3x=18 by itself because you have to add 1 to the 17 since you canceled it out of the equation then you are left with 3x=18 and you divide both sides by 3 and then 18 divided by 3 is 6 so x=6
Answer:
Step-by-step explanation:
p - 4p + 8 = 7p - 14
-3p + 8 = 7p - 14
-10p + 8 = -14
-10p = -22
p = 22/10
p = 2.2
The answer is b.
The length of the rectangle is 3w-150.
The width is w.
To get area you multiply length and width so w(3w-150)=70,200. The numbers in parentheses is the length.
You use distributive property and distribute the w to get 3w^2-150w=70,200.
You can simplify the equation by dividing both sides by 3 to get w^2-50w=23,400.
Then you get all the numbers on the left side of the equation by subtracting 23,400 to get w^2-50w-23,400=0.
Now that the equation equals zero, you can factor it to get (w+130)(w-180)=0.
Then you find the values for x with each factor which are x=-130 or x=180.
We would use the positive value for x because it is area.
You substitute 180 for x in 3w-150 and you would get 390.
