Answer:
Length = 5
Width = 21
Step-by-step explanation:
(x)(x + 16) = 105
x^2 + 16x = 105
x^2 + 16x - 105 = 0
(x - 5) x ( x + 21) = 0
x - 10 = 0
x = 5
x + 21 = 0
x = -21
Now that we have the zeroes.
We have to find the most viable one to put in.
Using -21 would not make sense, so we will use 5.
Plug it in:
x = 5
(5) (5 + 16) = 105
5 ( 21) = 105
A 9 kg bag of mangoes for $12 is.
Given is the bulk unit rate of the mangoes.
Let’s solve for the unit rate of each mango and its price.
=> Let’s analyze the given situation.
It is said that in 9 kilograms of bag of mangoes, the costs of all of it is 12 dollars.
Find how much the cost of 1 kg bag of mangoes is.
=> 12 dollars divided by 9 kilograms to get the value of 1kg bag of mangoes
=> 12 / 9 = 1.3
Thus, the unit rate is 1.3 dollars / kg
