Answer:
Step-by-step explanation:
6x + y = 30
-6x - 15y = 54
-14y = 84
y = -6
6x - 6 = 30
6x = 36
x = 6
(6, -6)
<span>Answers:
(12x^2 + 3x + 6) + (-7x^2 – 4x – 2) = 5x^2 - x + 4
(2x2 – x) + (-x – 2x2 – 2) = -2x - 2
(x3 + x2 + 2) + (x2 – 2 – x3) = 2x^2
(x2 + x) + (x2 + 8x – 2) = 2x^2 + 9x - 2

This is because
The triangle a c and e
Answer:
Assuming you're referring to the sides of a right triangle, the missing side X would be 12.
Step-by-step explanation:
The Pythagorean Theorem states that the two legs of a right triangle squared and added together is equal to the hypotenuse squared. 
is 169, 
is 25, 169 - 25 = 144. Take the square root of 144 and you'll get 12, which is the missing side of the right triangle.
since by the provided tickmarks WE ≅ ER, and QE ≅ ET, then both triangles are congruent by LL theorem, Leg Leg.
anyhow, since those legs are congruent, their hypotenuses must also be congruents, and we could use the HL theorem as well.
