Answer:
D
Step-by-step explanation:
A system of linear equations has infinite solutions when the graphs are the exact same line.
Therefore, the answer is D
Perimeter = (length+width) x 2
Let w units be the width of the rectangle.
Length of the rectangle = 2w
Perimeter:
(2w+w) x 2 = 60
(3w)2 = 60
6w = 60
w = 10
Area:
2(10) x 10
= 20 x 10
= 200 units
Answer:
x = 13
Step-by-step explanation:
x = ![\sqrt{x} a^{2} + b^{2}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20a%5E%7B2%7D%20%2B%20b%5E%7B2%7D)
12^2 + 5^2 = 13
