Answer:
x−2y
Step-by-step explanation:
you meant to put a parenthesis at the end right?
5n + 34 = -2(1 - 7n)
5n + 34 = -2 + 14n
5n = -36 + 14n
-9n = -36
9n = 36
n = 4
The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
Answer:
2
Step-by-step explanation:
As points, x-intercepts take the form

, so to find the intercepts we can set

and solve for

.

From the first equation alone, we already know that

is a solution, which means one intercept is

.
The second equation gives

so that the second intercept occurs at

.
So if

and

, we have

, giving C as the answer.
