A flowerbed is to be 3m longer than its width.the flowerbed will have an area of 70m²

1 answer:

4 0

ANSWER
Yes, it is a quadratic equation which is x² + 3x - 70 = 0

SOLUTION

Area = Length × Width
Let x be the Length, L = x
Length is 3 cm longer than its width, thus, W = x + 3
The Area is equal to 70m², thus, A = 70m²

In Mathematical representation,
A = L × W
70 = (x)(x + 3)
70 = x(x) + x(3)
70 = x² + 3x
0 = x² + 3x - 70

Sue Jones is insured for bodily injury in the amount of 10/20. She is at fault in an accident in which Albert Smith is injured.

Vlad1618 [11]

What you must do is add up the total amount of medical expenses:
Albert's medical expenses total $ 12,000
Sam's come to $ 8,000
Adding we have:
$ 12,000 + $ 8,000 = $ 20,000
Sue Jones is insured for the amount of 10/20
So:
(10/20) * (20000) = 10000
answer
The insurance will pay $ 10,000
