Step-by-step explanation:
NOT NEEDED FOR THIS QUESTION
Area of triangle=1/2(base×height)
360=1/2((4x-2)(7x+5))
720=(4x-2)(7x+5)
FOIL the binomial
720=28x^2+6x-10
Bring 720 to the other side
28x^2+6x-10-720=0
28x^2+6x-730=0
Factor 2 out
2(14x^2+3x-365)=0
Factor 2(14x+73)(x-5)=0
x-5=0
x=5
It can't be 14x-73=0 because the length can't be negative.
You're welcome.
Answer:
yes. The cost of the insurance is less than the probability cost of the operation
Step-by-step explanation:
yes. The cost of the insurance is less than the probability cost of the operation
The cost of health insurance = $1200
Cost of dramatic injury operation= $500,000
chances of need of operation= 47.3% over a 20 years period
the amount of pay insurance after 20 years=
probable of cost operation= 0.473*500,00= $236,500
clearly the cost of insurance is less than the probable cost of operation.
You're really just finding the volume of the cargo-carry part.
V= L x W x H
V= 8.3m x 3m x 4.2m
V= 104.58 m3 or 105 m3 (rounded)
ANSWER: The maximum volume of sand Billy's truck can carry is about 105 m3.
That would turn into 3x-5
