Answer:
72:48
Step-by-step explanation:
as you divide 120 by 5 as 3+2=5 and that equals 24
24x3=72
24x2=48
Answer:
2) (3,-2)
Step-by-step explanation:
the solution is where the lines intersect. they intersect at one point because this function is linear. they intersect at the point (3,-2)
Answer:
А.The system has two solutions, but only one is viable because the other results in a negative width.
Step-by-step explanation:
Given
Let:
length of play area A
width of play area A
length of play area B
width of play area B
Area of A
Area of B
From the question, we have the following:




The area of A is:

This gives:

Open bracket

The area of B is:


Substitute: 

Open brackets


Expand


We have that:

This gives:

Collect like terms


Using quadratic calculator, we have:
or
--- approximated
But the width can not be negative; So:

Answer:
x = ± 10
Step-by-step explanation:
Given
x² - 100 = 0 ( add 100 to both sides )
x² = 100 ( take the square root of both sides )
x = ±
← note plus or minus, hence
x = ± 10
