<span>Let the wall's length be y. So the fence parallel is also y.
We form the equation;
2x + y = 240
Now the area A is x*y, which is given as 5500.
We have 2 equations with 2 variables. Solve them and get the answer.
xy = 5500
2x + y = 240
Y = 5500/x
2x + (5500/x) = 240
2x^2 - 240x + 5500 = 0
x^2 - 120x + 2750 = 0
Work out the value(s) of x from above. </span>
Answer:
89 + 12/z
Step-by-step explanation:
We are adding 12/z to 89:
89 + 12/z
Answer:
12
Step-by-step explanation:
2(a+3)
Given a = 3, all you need to do is just plug in a = 3 into the expression
2(3 + 3)
= 2 (6)
= 12
Step-by-step explanation:
Substitute the value in the parentheses into x.
<u>When x = -2</u><u>;</u>
<u>When x = 0</u><u>;</u>
<u>When x = 5:</u>
