Answer: As given, relationship between the number of hours a plumber works and the total work fee she charges is proportional.
The meaning of proportional is Ratio of number of hours a plumber works and the total work fee she charges is constant.
Using Unitary method
5 hours of work = $350
1 hours of work = $70
Let number of hours worked = x hours
Amount earned for x hours of work is represented by = $ y
For , x hours of work amount earned = 70 x (x=1,2,3...)
→y= 70 x
→→
Step-by-step explanation:
A^2+b^2= c^2
16^2+ 28^2= c^2
square root of 256+784 = square root of 1,040
32.25=32.25
C= 32.25
I believe the equation is wrong
Answer:

Step-by-step explanation:
Given
(2m + 5n)² = (2m + 5n)(2m + 5n)
Each term in the second factor is multiplied by each term in the first factor, that is
2m(2m + 5n) + 5n(2m + 5n) ← distribute both parenthesis
= 4m² + 10mn + 10mn + 25n² ← collect like terms
= 4m² + 20mn + 25n² ← perfect square trinomial
