Answer:
x = 10
Step-by-step explanation:
Step 1 : Collect like terms and simplify
Step 2 : Divide both sides of the equation by 2
Step 3 : Simplify by cross cancellation of common term : 2
Answer:
110
Step-by-step explanation:
Using pythagorean theorm
c^2 = a^2 + b^22
610^2 = 600^2 + b^2
372100 = 360000 + b^2
b^2 = 12100
b = 110
I'm not completely sure but this is what I would do.
evaluate <span>(1/ 4)^x - 1 </span>as is. But change the (1 /2)^2x to (2/4)^2x. This way both fractions have the same denominator and in this sense, the same base. The 2/4 base still evaluates into 1/2 so nothing, mathematically, is being broken here.
You can line them up underneath each other and skip count is one way like this :
2; 2,4,6,8,10
4; 4,8,12,16,
and your answer would be 8 because it is a common number between 2 and 4
