-7 + 9  \neq  9 + 7

2 \neq 17

When you add a positive number and a negative number, you get a positive, but the number is smaller. If you add two positive numbers, then of course, you're going to get a positive number as an answer. But overall, this is false.

Please answer !! what is the factorization of the trinomial below ?
Alex_Xolod [135]
Since we always want to have an a which equals 1 so then we don't have to do AC method, a longer process, we're going to want to take out the -1.

-1(x^2 - x - 42)

Then, we want to know what two number multiply to equal c (-42 here) and add up to equal b (-1 here). Those two numbers would be -7 and 6 since -7(6) = -42 and -7 + 6= -1.

So then from here we can just plop these numbers into (x+ __).

1(x-7)(x+6)

This is your final answer, A.

-4 ( -3 + 7v )= -7v + 33
PSYCHO15rus [73]

Answer:

v = -1

Step-by-step explanation:

-4 (-3 + 7v) = -7v + 33

12 -28v = -7v + 33

-12 -12

-28v = -7v + 21

-28v + 7v = 21

-21v = 21

-21÷-21 = 21÷-21

v = -1
