Answer:
For longest x = 6.4
For shortest x = 3
Step-by-step explanation:
Given a right angle triangle with lengths 4 units and 5 units and x units .
x can be gotten using Pythagoras theorem .
If x Is the longest side , then
x^2 = 5^2 + 4^2
= 5x5 + 4x4
= 25 + 16
x^2 = 41
x = squared root of 41
x = 6.4
If x is the shortest side ,
x^2 = 5^2 - 4^2
= 5x5 - 4x4
= 25 - 16
x^2 = 9
x = squared root of 9
x = 3

Answer:
(x) = √ x + 4
Step-by-step explanation:
step 1) replace f(x) with y
y = x² - 4
step 2) switch the x and y (because every (x, y) has a (y, x))
x = y² - 4
step 3) add 4 to both sides of the equal sign
x + 4 = y²
step 4) take the square root of both sides of the equal sign (the square root symbol cancels out the ²)
√ x + 4 = y
step 5) you know have the inverse of f(x) = x² - 4
(x) = √ x + 4
Divide 4 by 12, which equals approximately 0.33333, then multiply that to 180, which gives us 60. So she sold 180 ears of corn for $60.
