Answer: 12.1 ft
Step-by-step explanation:
A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.
c² = a² + b²
Where:
c = hypotenuse
a = base
b = Height
c² = 11² + 5²
c² = 121 + 25
c² = 146
c = √146
c = 12.1 ft
Answer:
44
Step-by-step explanation:
Given, 3x^2 + 3y^2 = 42
=>3(x^2 + y^2) = 42 =>x^2 + y^2 = 42/3= 14
Thus,
= (x - y)^2
= x^2 + y^2 - 2xy
= (x^2 + y^2) - 2xy
= 14 - 2(-15)
= 14 + 30
= 44
