I need help can I don’t know how to do this problem

a ^ (1/12)

Step-by-step explanation:

a ^ (1/3)

a ^ (1/4)

We know that b^ c / b^ d = b ^ (c-d)

a^ (1/3 - 1/4)

getting a common denominator

1/3 *4/4 - 1/4*3/3 = 4/12 - 3/12

a^ (4/12 - 3/12)

a ^ (1/12)

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
