Here is the first sign that should tell you this isn't a rectangle.
d=_/w^2+l^2 is the equation to solve the diagonal of a rectangle
if you plug in 21 and 20, d would equal 29 not 28 so for that reason alone it is not a rectangle.
I am about 90% sure the correct answer is B. I hope this helps let me know if I was right.
Option B!
Answer: x=3.6; y=-2.5
Step-by-step explanation:
To solve this pair of equations, we can use elimination method.
5x+4y=8
10x-4y=46
Add both equations together to cancel out 4y.
15x=54 [divide both sides by 15]
x=3.6
Now that we know x, we can plug it back into any equation to find y.
5(3.6)+4y=8 [multiply]
18+4y=8 [subtract both sides by 18]
4y=-10 [divide both sides by 4]
y=-2.5
Now, we have x=3.6 and y=-2.5.
