Correct answer only ! i cannot retake what is the exact solution to the equation 2^x+2 = 5^2x ?

Its A

Step-by-step explanation  

2^(x + 2) = 5^2x    By the laws of logs:-

(x + 2)ln2 = 2x ln5

x ln2 + 2ln2 = 2x ln5

2x ln5 - x ln 2 = 2ln2

x =  2 ln2 / ( 2 ln5 - ln 2)  (Option A)

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
