2x - 5 = 8 Add 5 on both sides
2x - 5 + 5 = 8 + 5
2x = 13 Divide 2 on both sides to get "x" by itself
x = 
So addition and division
Answer:
x = 8
z = 93°
You had to solve the equation 13x-17=14x-25 and than solve {360-(87*2)} /2
Answer:
1. -8x² - 16x - 6 a = -8, b = -16, c = -6
1. 4x² - 1 a = 4, b = 0, c = -1
Step-by-step explanation:
use the 'foil' method:
(4x + 2)(-2x - 3)
F: -8x² O: -12x I: -4x L: -6
-8x² - 16x - 6
(2x + 1)(2x - 1)
F: 4x² O: -2x I: 2x L: -1
4x² - 1
