Answer:
This is quadratic trinomial
Step-by-step explanation:
It has x^2 (square) and consists of 3 parts
Simplify it to 6v=12
divied 12 by 6
v=2
X ·2 = 12x - 15
2x = 12x - 15
2x + (-12x) = (12x - 15) + (-12x)
Result: x = 3/2
Using a calculator I put 1,284/26=49.384615385. Rounded to tenth: 49.4 :)
12. 360-140=220 x+12=220 x=208
13. 360-8=352 x-47=352 x=399
14. 360-80=280 2x+10=280 x=135
15. 125-64=61 x=61
16. 167-88=79 x=79
