Step-by-step explanation:
We require 2 equations with the repeating 3 placed after the decimal point.
let x = 0.5333.. ( multiply both sides by 10 and 100 )
10x = 5.333... → (1)
100x = 53.333... → (2)
Subtract (1) from (2) tus eliminating the repeating 3
90x = 48 ( divide both sides by 90 )
x =
= 
Answer:

Step-by-step explanation:
First we need to compute the side length as a function of h
So x be the side length of the right isosceles triangle, in Pythagorean formula we have



The cost for the legs is

The cost for the hypotenuse is

So the total cost in term of h is

Step-by-step explanation:
Diego is correct they have to be similar
Answer:
x^2 +4x -4
Step-by-step explanation:
f(x) = 4x+1
g(x) = x^2 - 5
f(x) + g(x) = 4x+1 + x^2 -5
= x^2 +4x -4
