Answer:
x=2 meters
Step-by-step explanation:
length = 12+2x
width = 6+2x
Area = (12+2x) (6+2x) = 160
Foil
72 + 12x+24x+4x^2 = 160
Combine like terms
4x^2 + 36x +72 = 160
Subtract 160 from each side
4x^2 +36x -88 =0
Divide by 4
x^2 +9x -22=0
Factor
What 2 numbers multiply to -22 and add to 9
11 * -2 = -22
11+ -2 = 9
(x +11) (x-2) =0
Using the zero product property
x=-11 x=2
Since we cant have negative length
x=2
Answer:

Step-by-step explanation:
Answer:
ABC = 60
BCA = 90
CAB = 30
Step-by-step explanation:
5x+9x+6+90 = 180
5x+9x = 84
14x = 84
x = 6
5x = 30
9x+6 = 60
The inverse of the function f(x) = 4(x-3)² + 2 is
The given function is:
f(x) = 4(x - 3)² + 2
To find the inverse of the function:
Make x as the subject of the formula
Replace x by and replace f(x) by x
Therefore, the inverse of the function is:
