Let width = x, Therefore the length must equal 2x
Therefore insert these values on the sides of a rectangle.
Add: 2x + 2x + x + x = 18
Therefore 6x = 18
x = 3
Answer:
X in math doesn’t have a value it’s an unknown number good luck though
Step-by-step explanation:
AD = AB
AD = 2r+8
AB = 5r-13
we need to find the value of r to find the total length
so 2r+8 = 5r-13
subtract 2r from each side:
8 = 3r -13
add 13 to each side:
21 = 3r
divide both sides by 3
r = 21 / 3 = 7
r=7
now we know r, so replace r with 7 in the equation for AD
AD = 2r+8 = 2(7) +8 = 14 +8 = 22
the answer is D. 22
