Length of rectangle is 5 times it’s width the perimeter is 96cm what is the area

320cm.²

Step-by-step explanation:

= 5

2 + 2[5] = 96 ↷

2 + 10 = 96 ↷

12 = 96 ↷

= 8 [plug this back into the top equation to get 40 units]

[8][40] = 320 [Area]

I am joyous to assist you anytime.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
