Answer:
he made 6 deliveries.
subtract $4.25 from his total, $17.15. you get $12.9. then divide that by $2.15 and it gives you 6.
Answer:
B. EF
Step-by-step explanation:
The triangle above is a right triangle, these consist of 2 legs and a hypotenuse. The hypotenuse is always the longest side so EF is the answer.
<span>L = 2W + 5
A = LW = 63
L = 63/W
W=63/L
L = 2W + 5
63/W = 2W + 5
63 = 2WW + 5W
2WW + 5W - 63 = 0
2WW + 5W - 63 = 0
is already in quadratic equation form: ax^2 + bx + c = 0
use the quadratic formula to solve for two solutions:
x = ( -b +- sqrt( bb - 4ac ) ) / 2a
the two solutions are:
x = 9/2
x = -7
you cant have a negative solution for length so use the positive one
solve for length:
L=5+2(9/2)
L=5+18/2
L=5+9
L=14
W = 9/2
L = 14</span>
