The answer is B x = -4. x= 3
You must factor the equation by find what 2 numbers can multiply to equal -12 and add to equal 1.
-3 and 4 are the two numbers. Now to put it in factor form would be:
(x - 3)(x + 4) = 0
They y also must equal zero.
Since its equals to 0, we must solve for x for the binomial.
x - 3 = 0 ; x = 3
x + 4 = 0 ; x = -4
The answer you get from solving x, is that answer
I think the answer is 180 but im not 100% on that
Answer:
16
Step-by-step explanation:
Average = the sum of all numbers divided by the amount of items in the set, so:
10+30=40
40/2=20
20-4=16
Hopefully this helps :) Good luck!
Answer:
a=-13
Step-by-step explanation:
16−5a+2a−1=41−a
16-1-41 = 5a-2a-a
-26 = 2a
a= -26/2
a=-13
