now again the problems that will do if u understnad them?

Question

now x=2
1.4x+9x+8x=
2.-6x+11x+(-2x)=
3.-3x+8+2x+(-3)=
4.11x+(-5)-3x=
5.-13x+15x-6=

Answer 1

now x=2

1.4x+9x+8x=
4(2)+9(2)+8(2)
8+18+16
8+34
42

2.-6x+11x+(-2x)=
-6(2)+11(2)+-2(2)
-12+22+-4
-12+18
6

3.-3x+8+2x+(-3)=
-3(2)+8+2(2)+(-3)
-6+8+4+(-3)
-6+12+(-3)
6+(-3)
3

4.11x+(-5)-3x=
11(2)+(-5)-3(2)
22+(-5)-6
22+ (-11)
11

5.-13x+15x-6=
-13(2)+15(2)-6
-26+30-6
4-6
-2

Answer 2

1. 4(2) + 9(2) + 8(2) = 8 + 18 + 16 = 42

2. -6(2) + 11(2) - 2(2) = -12 + 22 - 4 = 22 - 16 = 6

3. -3(2) + 8 + 2(2) - 3 = -6 +8 +4 -3 = 12 - 9 = 3

4. 11(2) - 5 - 3(2) = 22 - 5 - 6 = 22 - 11 = 11

5. -13(2) + 15(2) - 6 = -26 + 30 - 6 = 30 - 32 = -2

Answer 3

1 = 42
2= 6
3= 0
4= 11
5 =50

Answer 4

its really rather simple. since x equals two then put it in for question one it would look like this
4x2=8
9x2=18
8x2=16
once you have these numbers then add them up which will look like this
8+18+16=42
for question 5
-13x2=-26
15x3=30
-6= is just simple negative six
your problem will now look like this
-26+30-6=-2

Answer 5

1. 42
2. 6
3. 7
4. 0
5. -2

Answer 6

Remember your order of operations:

PEMDAS!

parentheses, exponents, multiplication, division, addition, subtraction

Figure out what to do for each problem.

Hint for #1, all are something x so you can just add them.

Answer 7

1.) 42
2.) 6

I would figure the rest out, but I gotta go...sooorrrryyy

Answer 8

yep - I understand them -
but if I do you homework - you won;t - - - - - - -
and test time comes - you are in deep trouble
