Answer:
-88
Step-by-step explanation:
-a² + 4ab - b²
Substitute the variables with the numbers given.
-2² + 4(2×-6) - -6²
-2² + 4(-12) - -6²
-4 + 4(-12) - 36
-4 + -48 - 36
-52 - 36 =
-88

Answer:
2 pages per minute.
Step-by-step explanation:
40 pages / 20 minutes
= 40 / 20 = 4 / 2 = 2
Therefore, you read 2 pages per minute.
x^2+6x-5=0
x^2=2x
2x+6x-5=0
2x+6x=8x
8x-5=0
+5 +5
(if you don’t know what I’m doing here is that I’m removing the negative 5 by putting a positive 5 since both of them make 0. Also the “x” always stay alone and the unit stays as the unit)
(I putted the positive under the 0 because what u do to the unit you need to do the same thing with the other.)
8x/8=5/8
(If ur lost here it means dividing.)
The answer
X=0.625
(btw I’m not really sure if this is right so um don’t really trust me in this lol)
