The current area is 15 x 9 = 135 square feet.
He wants to increase both the length and width by X:
Set up an equation:
(15 +x) * (9 +x) = 135 * 2
Simplify :
x^2 + 24x + 135 = 270
Subtract 270 from both sides:
x^2 + 24x - 135 = 0
Use the quadratic formula to solve for x:
-24 +/- √(24^2 - 4(1*-135) / 2*1
x = 4.7 or -28.7
The answer has to be a positive value, so x = 4.7 feet.
(3x − 5) − (4x + 6)
to simplify combine like terms
= (3x - 4x) + (-5 - 6)
= -1x - 11 (same as -x - 11)
ANSWER: -1x - 11 (first choice)
Hope this helps! :)
Step-by-step explanation:
Hey there!
Given;
f ( x ) = x² + 2x - 1
g ( x ) = 3x - 2
To verify:
LHS:
~ Insert "2" instead of "x".
Simplify it;
Therefore; (f/g)(2) = 7/4.
RHS:
~Insert "2" instead of"x".
Simplify it.
Therefore, f(2)/g(2) = 7/4.
Since (f/g)(2) = f(2)/g(2) = 7/4.

−2(6x+5)=74
Simplify both sides of the equation.
−2(6x+5)=74
−2 x 6x−2 x 5=74
−12x−10=74
Add 10 to both sides.
−12x−10=74
+10 +10
−12x=84
Divide both sides by -12.
−12x
=
84
/−12 /-12
x=-7
hope it helps!
Answer: X can not be 11 or higher, so that means this problem will be 10 or lower. There for the value of X=6
