Find the area of the shaded region
A. 571
B. 531
C. 154
D. 377
E.725

A. 571

Step-by-step explanation:

By adding the radius of both of the inner circles, you can find the radius of the larger circle. (20)

Continue by finding the area of both inner circles using the formula

A= 3.14 * radius².

A= 3.14 * 169      A= 530.66 (Area of circle with 13m radius)

A= 3.14 * 49       A= 153.86 (Area of circle with 7m radius)

Add those together to find the combined area  (Combined area = 684.52)

Find the area of the large circle

A= 3.14 * 400     A= 1256

Subtract the combined area from the large circle to find the area of the shaded region

1256 - 684.52 = 571.48

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
