Lines y = −2x + 3 and y = 3x – 5 intersect the x-axis.
Since -6 +6 can be rearranged to 6-6 using the communicative property, we get 6-6 =0 . In addition, -120+(-6) is essentially having -120+ 1*(-6), and 1 times a number is simply that number, so we have -120-6=-126
Step-by-step explanation:
Let x represent the missing sides measurement.
x+x+28=52
combine like terms
2x + 28 = 52
subtract 28 from both sides
2x + 28 = 52
- 28 - 28
2x = 24
divide both sides by 2
x = 12
plug it back in
one leg is 12 inches
the other leg is 40 inches
(x - 3) + (x - 6) + x = 63
x - 3 + x - 6 + x = 63
Combine like terms
3x - 9 = 63
Isolate the constant
3x - 9 + 9 = 63 + 9
3x = 72
Isolate the viable
3x / 3 = 72 / 3
x = 24
