GCF of 85 is 100 53+32=85 the gcf of that is 100
3(x+4)=36
What you need to do is divide both sides of the equation by 3 in the first part
x+4=12
Now you move the constant towards the right side and change the sign
x=12-4
Subtract the numbers to find the answer
x=8, therefore to solve 3(x+4)=36 it will give you x=8 as your answer. Hope this helps ^^
The formula in computing the area of the circle is:
A = pi (r)^2
Where r = the radius of the circle
Since you are only given the diameter of the circle, you
have to solve for its radius. The radius of the circle is half its diameter. Therefore,
the radius of the circle is 5 (10/2).
Now, you substitute the measurements to the formula:
A = 3.14 (5)^2
A = 3.14 (25)
A = 78.5 sq. units
In order from top to bottom the answers are a,d,c,d
I hope this helped!
