Answer:
=5x^2+4x−5
Step-by-step explanation:
Let's simplify step-by-step.
3x2−5x+1+2x2+9x−6
=3x2+−5x+1+2x2+9x+−6
Combine Like Terms:
=3x2+−5x+1+2x2+9x+−6
=(3x2+2x2)+(−5x+9x)+(1+−6)
=5x2+4x+−5

Answer:
jhfjdhsuhufhre
Step-by-step explanation:
a) 3x+2(41-5x)=33 as y=41-5x is given
3x+82-10x=33
-7x+82=33
-7x=33-82
-7x=-49 cut the negative signs as its LHS and RHS
x=49/7=7
b)-5x+3(3x-3)=3 as y=3x-3 is given
-5x+9x-9=3
4x-9=3
4x=3+9
x=12/4=3
c)4x+11-5x=9
-x+11=9
-x=9-11
-x=-2 cut the negative signs as its LHS and RHS
x=2
d) 5y+ -5-2y=-11 as x=-5-2y is given
3y+-5=-11
3y=-11+5
3y=-6
y=-6/3=-2
e)-5x-4(2x+1)=35 as y=2x+1
-5x-8x+4=35
3x+4=35
3x=35-4
3x=31
x=31/3
x=10.3
Answer:
the answer is any number above 18
