Step-by-step explanation:
If the radius of a circle is doubled, the area of the circle will be quadrupled and the circumference will also be doubled. This makes sense because the area of a circle is directly proportional to the square of the radius of the circle (if the radius of a circle is increased x times, its area will be increased to x^2 times the original area), whereas the circumference is proportional to the size of the radius (if the radius of a circle is increased x times, its circumference will increase x times).
8. True or false: in order to solve the following equation, you would first subtract by 4, then multiply by 5/1 *
4+1/5=-1
To solve 3x + 2 = 23 you must:
Subtract 2 from both sides so like this 3x+2−2=23−2 and get 3x=21.
Now Divide both sides by 3 so 3x/3=21/3. Mainly divide 21/3 and get 7.

To solve -2y - 7 = 3 you must:
Add 7 to both sides so like this −2y−7+7=3+7 and get −2y=10.
Now Divide both sides by -2 so -2y/-2=10/-2. Mainly divide 10/-2 and get 5.
