D because a trapezoid has four sides and the top and bottom are parallel
Use the formula (b/2)^2 in order to create a new term. Solve for x by using this term to complete the square.
x = 1 ±
Step-by-step explanation:
P = IV
2000 W = I (120 V)
I = 16.7 A
P = E/t
P = (2000 W × 8 hr) / (1 day)
P = 16,000 W·hr/day
P = 16000 W·hr/day × (365 day / yr)
P = 5,840,000 W·hr/yr
P = 5,840,000 W·hr/yr × (1 kW / 1000 W)
P = 5840 kW·hr/yr
C = 5840 kW·hr/yr × (0.25 $/kW/hr)
C = $1460/yr
Y² + 10z - 10y - yz = (y - 10)(y - z)
