The answer you will get is 15, all you do is just substitute the number into the equation and then you simplify
Answer: x=40
Step-by-step explanation:
Answer:
The line of symmetry is x = 8
Step-by-step explanation:
To find the line of symmetry in an absolute value function, look to the base formula.
f(x) = alx - hl + k
In this equation, h is the line of symmetry. Therefore, we know it to be 8
Given that the length should be 3ft longer than twice the width, the equation that will be used to get the width will be as follows;
let the width be w;
the length will be:
(2w+3)
hence the area will be:
w(2w+3)=90
2w^2+3w-90=0
thus the above equation can be used to find the value of w
