Math question quadratics
denpristay [2]

Answer: The length and width are 50 and 30 meters (or 30 and 50 meters).

Step-by-step explanation:

To solve this question, we can represent variables for the length and width in two equations.

2l + 2w = 160\\\\l * w= 1500

To solve for one of the variables, you'll have to substitute one of the variables, so solve for one of them:

2l = 160 - 2w\\l = 80 - w

(80-w)*w=1500\\\\-w^2 + 80w - 1500 = 0\\\\w^2 - 80w + 1500 = 0

Now, we have a standard quadratic equation that we can factor. When factoring, you'll get this:

(w-50)(w-30) = 0

This tells us that the width could be either 50 or 30.

Substitute 50 into one of the equations to find the length:

2 (l) + 100 = 160

l = 30.

The length and width are 50 and 30 meters (or 30 and 50 meters).

< Last spring, Kai planted a total of 9 green peppers and tomatoes in the community garden.
ExtremeBDS [4]

Answer:

Step-by-step explanation:

Let x = the number of pepper plants, then (x + 6) = the number of tomato plants. Since the ratio of tomatoes to peppers is 5:2, we have the following:

5/2 = (x + 6)/x

2x + 12 = 5x

12 = 3x

4 = x = the number of pepper plants

Klio2033 [76]
Well this is simple all you have to do is subtract 6 dollars from 35 lets do that first
35 - 6 = 29 
so she has 29 dollars to spend on each friend and she only has two....
so lets divide 29 and 2
29/2 = 14.5 
so she can spend $14.50 on each of her friends:)
