Distance = speed X time
distance in heavy traffic = 40mph X 1hour = 40miles
distance in light traffic = 60mph X 3hours = 180miles
Total distance = 180 + 40 = 220miles
Step-by-step explanation:
34 = 2(w + w-3)
solving for 'w' we have w=10
10-3 = 7
the width of the window is 10 feet, its length is 7 feet
Answer:
a(12) = 61
Step-by-step explanation:
a(n)=-5+6(n-1)
let n =12
a(12) = -5 +6(12-1)
a(12) = -5 +6 *11
a(12) = -5 +66
a(12) = 61
First, rearrange the quadratic equation:
5x² + 9x - 4 = 0
Now, compare it to the general quadratic equation:
a<span>x² + bx + c = 0
Therefore you get:
a = +5
b = +9
c = -4
And the quadratic formula will be:
x = [-b +/- </span>√(b² - 4ac)] / 2a
= [ -5 +/- √(81 - 4·5·(-4))] / 2·5
= (-5 +/- √161) / 10
