Step-by-step explanation:
8.9x-5 and -6.8x+8
8.9-6.8 + -5+8
2.1x+3
This is probably way overcomplicated but i cant remember how to do it
w = n
l = 2n+1
w*l = 66
n(2n+1) = 66
2n^2 + n =66
2n^2 + n - 66 = 0
using quadratic equation
n = 11/2
width = 11/2 = 5.5
length = 11 + 1 = 12
Answer:
D=M/V
D=65.1/6.2
