Answer:
Solution set = {25}
Step-by-step explanation:
=> 
Dividing both sides by -1
=> 
Taking square on both sides
=> x = 25
<em><u>Solution set = {25}</u></em>
If the diameter is 8 centimeters, the radius is 4. We can use the formula

and plug in r=4 and h=13 to get

, so

.
Answer:
40%
Step-by-step explanation:
1299-725= 574
574/1299 x 100 = 44.19%
F(x) = kx
12 = 8k
k = 12/8 = 3/2
Required equation is f(x) = 3/2 x
Answer:
7(6m - 4) = -364
multiply 7 for both variables in the parenthesis
42m - 28 = -364
move 28 to other side
42m= -336
divide 42 on both sides
m= -8
