20 POINTS PLEASE HELP Which of the following expressions is true? A. 2^4 • 2^3 = 212 B. 3^3 • 3^6 > 3^8 C. 4^2 • 4^2 > 4^4 D. 5^5 • 5^2 = 5^10

Step-by-step explanation:

Exponents of the same base add

A. 2^4 • 2^3 = 212

     2^7  =  128 ≠  212

B. 3^3 • 3^6 > 3^8

         3^9  >  3^8        

C. 4^2 • 4^2 > 4^4

        4^4  =  4^4

D. 5^5 • 5^2 = 5^10

           5^7   ≠   5^10

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
