Your answer would be

A. Adding 7x to both sides of the equation

And in doing so, you'd start your first step to having "like terms" on "like sides"
by having all "x's" on the right side of your equivalent sign "="

A triangle has sides with lengths of 4 yards, 10 yards, and 11 yards. Is it a right triangle?

vodka [1.7K]

Answer:

Step-by-step explanation:

for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse

a² + b² = c²

in this problem, 4² + 10² ≠ 11²

16 + 100 ≠ 121

What is the midpoint of the line segment with endpoints (-1,7) and (3,-3)

blsea [12.9K]

Hey there!!

Co-ordinates for midpoint when two endpoints are given :

... $\frac{x2+x1}{2} , \frac{y2+y1}{2}$

Given endpoints :-

... ( -1, 7 ) ( 3, -3 )

... $\frac{3-1}{2},\frac{-3+7}{2}$

... $\frac{2}{2},\frac{4}{2}$

... $1,2$

<u><em>Hence, the midpoint is ( 1,2 ) </em></u>

Hope my answer helps!
