Answer:
Step-by-step explanation:
x² - 6 = 10
x² = 10+6
x² = 16 = 4 * 4
x = 4

Answer:
1200feet
Step-by-step explanation:
Given the the road's curve elevation modeled by the equation
y = 0.00005x^2 - 0.06x,
x is the horizontal distance in feet between the points where the road is at sea level and;
y is the elevation
The elevation the road is equal to sea level when y = 0
Substitute y = 0 into the equation and calculate x;
0 = 0.00005x^2 - 0.06x
0.06x = 0.00005x^2
0.06 = 0.00005x
x = 0.06/0.00005
x = 1200 ft
Hence they will place the stop sign at a horizontal distance of 1200feet

(This is a little difficult but I've got it)
((x - 45)/12) + 20 = 5(32 - x)
(I made the equation a little more complex than I should have but that equation should still work if you were to solve for x)
