5(x + 3) + 9 = 3 (x - 2) + 6
5x + 15 + 9 = 3x - 6 + 6
5x + 24 = 3x
5x - 3x = -24
2x = -24
x = -24/2
x = - 12
Perpendicular lines form 90 degree angles.

231 chairs because 9 times 25 is 225, plus 6 is 231
Slop=(y2-y1)/(x2-x1)
Slop=(-6-(-4))/(7-4)
Slop=-2/3
Answer:
29.2 cm
Step-by-step explanation:
The two leg lengths are 15 and 25 cm and we are to find the length of the hypotenuse. The Pythagorean Theorem applies here because this is a right triangle.
a^2 + b^2 = c^2 becomes 15^2 + 25^2 = 225 + 625 = 850
The hypotenuse length is thus √850 ≈ 29.2 cm
