Answer:
if breadth is y feet long
let length be y+4
Step-by-step explanation:
therefore,
area=(4+y)*y
area=4y+y2
Answer:
F
Step-by-step explanation:
Bob charges $140
Andy charges $135
Andy is cheaper
f(x) = 5x²
f(10) = 5(10)² = 5(100) = 500
f'(x) = 10x
f'(10) = 10(10) = 100
Now, find the line that passes through (10, 500) and has a slope of 100
y - y₁ = m(x - x₁)
y - 500 = 100(x - 10)
y - 500 = 100x - 1000
y = 100x - 500
It is undefined so i think it would be no
