Answer:
x = 2
Step-by-step explanation:
How to find "x"
3x = 4 + 2(3 - x) *Remove the parentheses*
3x = 4 + 6 - 2x *Calculate*
3x = 10 - 2x *Move the variable to the left*
3x + 2x = 10 *Collect the terms*
5x = 10 *Divide both sides*
x = 2
I hope the helped!!!
70 degrees, hope this helped.
2(x - 4) + 7(x + 4)
(2x - 2 • 4) + (7x + 7 • 4)
9x + 20
By definition, the circumference of a circle is:

The area of a circle is:

Where,
r: radius of the circle.
When the radius is double, then the new area is:

Rewriting we have:

In terms of a we have:
