Hi I need help with 4 problems you don't have to answer all of them just the ones you think you might know and I need to know how to do it. The questions are below:) 1. -3x + 10
2. 4x +8
3. -1 - 4x
4. 7 -5x

1.    -30x     2. 12x    3.   x         4.  2x

Step-by-step explanation:

i believe the way your learning is that you have to add or subtract both numbers and then add the letter next to the answer.  number 3 is just x because -1- 4x = 0 and just add the x.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
