Answer:
393.75
Step-by-step explanation:
to find the volume of a rectangular prism, multiply all values by each other.
Combine 35 and x . Since the equation can be written in the form y=kx y = k x , y varies directly with x and k . The constant of variation, k , is 35 .
Answer:
7.94
Step-by-step explanation:
Answer:
x =
Step-by-step explanation:
Square both sides.
y² = (2x + 1) / (x - 1)
Multiply both sides by (x - 1).
y²(x - 1) = 2x + 1
xy² - y² = 2x + 1
xy² = 2x + 1 + y²
xy² - 2x = 1 + y²
x(y² - 2) = 1 + y²
x =
