Answer:
choice C: x2 -3x -3
Step-by-step explanation:
(3x^2-7x+2)-(2x^2-4x+5)
becomes
3x^2-7x+2 -2x^2+4x-5
adding
3x^2-2x^2 -7x+4x +2-5
which is
x^2 -3x -3

Answer:
I will help you with the first one
Step-by-step explanation:
x= -3 -2 -1
y= -4 -3 -2.59
[42 ÷ (2 + 3 • 2)] + [4 • (36 – 52)]
[42÷(2+6)]+[4×(-16)]
[42÷8]+[-64]
[5.25]+[-64]
5.25-64
-58.75
