Answer:
40/3, 172/3, respectively
Step-by-step explanation:
x + 9 = 2y
2x = 2y + 2
x + 9 = 2(2x - 2)
4x - 4 = x + 9
3x - 13 = 0
x = 13/3
y = 40/6
RT = 13/3 + 9 = 40/3
QS = 160/3 + 4 = 172/3
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:
<h2>n = 72</h2>
Step-by-step explanation:
Using the addition property add 7 to both sides
That's
Next multiply both sides by 3 to eliminate the fraction
That's
We have the final answer as
<h3>n = 72</h3>
