Answer:
12
Step-by-step explanation:
2x - 4= 16
Divide by 2
2x/2 -4/2 = 16/2
x -2 = 8
Add 4 to each side
x-2+4 = 8+4
x+2 = 12
Find the area of the circle
A of circle = πr²
radius = diameter/2 = 48/2 = 24
Area = (3.14)(24)²
Area = 1808.64 in²
Hope this helps :)
(F*g) means f ( g(x) ) . Knowing this we can say
F(g(x)) = 3(5-x) ^2
= 3 (5-x)(5-x)

Answer:
b 5.2 *10-4
Step-by-step explanation:
.00052
We are moving the decimal 4 places to the right to make it in scientific notation. This puts it in the form a* 10^b a must be between 1 and less than 10 and b is the number of places we moved it. It we move it to the left it is positive and to the right it is negative.
5.2 *10-4
It would be 170 because you just add a zero at the end since the number only changed by adding one zero.
