8*(1/x) = 4*(1/8)
8/x = 4/8
64 = 4x
x = 16
4y(3y + 9)
12y + 36
36 ÷ 12=x=3
Answer:
Factor:
x^2+5x-300=0
(x-15)(x+20)=0
x=15 is the width
x+5=20 is the length
Step-by-step explanation:
Given:
weight of mixture : 1792 ounces
output of mixture : 560 bars of soap
to get the weight per unit, we simply divide by total weight by the total number of output.
