Answer:
a = 
Step-by-step explanation:
4a -16 = a - 15
both left and right -a
then
4a - 16 -a = a - 15 -a
then
4a -a -16 = a -a -15
then
3a -16 = -15
both left and right + 16
then
3a -16 + 16 = -15 + 16
then
3a = 1
both left and right ÷3
then
3a ÷ 3 =1 ÷ 3
then
a =
Do you need that rewritten ?
A or area will increase as r increases.
r^2 = r×r which means the r value is doubling increasing the area
P = A(1+i)ⁿ, where:
A= initial value
I = interest in %
n= period of compound investment.
However, if the interest is paid twice a year, that means you have to divide the interest by 2 and the period becomes twice n
P = 875(1+9.5%/2)⁵ˣ²
P = 875(1+4.75%)¹⁰
P =875( 1.0475)¹⁰
P = $1,391.7
The answer is 20 because perimeter is adding all the sides so 12 + 8= 20
