Answer:
<em>x is 12 and y is 3</em>
Step-by-step explanation:
Given a parallelogram LMNO,
LM = ON and OL = NM
Given;
ON = 9x - 8
LM = 8x + 4
NM = x - 8, and
OL = 3y - 5
Substitute into the expression
LM = ON
8x + 4 = 9x - 8
8x - 9x = -8 - 4
-x = -12
x = 12
Also OL = NM
3y - 5 = x - 8
3y - 5 = 12-8
3y - 5 = 4
3y = 4+5
3y = 9
y = 9/3
y = 3
<em>Hence the value of x is 12 and y is 3</em>

Answer: 12.6 m
Step-by-step explanation:
Use the pythagorean theorem, we get that the height, or x, is
sqrt(22x22-18x18) = sqrt(484-324) = sqrt(160) = 4sqrt(10) = 12.6 m
The correct option is (B): (3x+2)(3x+1)
Explanation:
Add all the boxes:
9x^2 (boxes)
9x (boxes)
The constants = 2
So it becomes:
9x^2 + 9x + 2
9x^2 + 6x + 3x + 2
3x(3x+2) + 1(3x+2)
(3x+2)(3x+1)
Answer:
28 m
Step-by-step explanation:
full roll length: r
Ryan bought: r/4
He trimmed 2 m: r/4 - 2
Length left: 5
r/4 - 2 = 5
r/4 = 7
r = 28
Answer: 28 m
