Answer:
c = 169
Step-by-step explanation:
We can use FOIL to determine this after factoring out the equation.
(x+13)(x+13)
F: (x*x)
O: (x*13)
I: (13*x)
L: (13*13)
x^2 + 26x + 169
Answer: 8/9
Step-by-step explanation:
3x/7 = 8/21, find x
Step 1: cross multiply the equation
3x × 21 = 8×7
63x = 56
Divide both sides by 63; retain in fraction.
x = 56/ 63
x = 8/9
If it costs $12.5 for every GB and we use 8 then 12.5*8=$100. So if our flat rate now is $70 we would loose 100-70=$30
So Maria would loose $30 a month if she pays per GB
Answer:
12π
Step-by-step explanation:
Volume of the cone is πr^2 * h / 3
r = 3
h = 4
9π * 4 / 3 = 12π
