Answer:
<h2>-7</h2>
Step-by-step explanation:
Simplify the equation first:
8x+56=0
-56 on both sides
8x=-56
-56/8=-7
That's your answer: -7
Answer:
-9
Step-by-step explanation:
Simplify the following:
-6×(-2)/4 (-3)
-6×(-2)/4 (-3) = (-6 (-2) (-3))/4:
(-6 (-2) (-3))/4
The gcd of -2 and 4 is 2, so (-6 (-2) (-3))/4 = (-6 (2 (-1)) (-3))/(2×2) = 2/2×(-6 (-1) (-3))/2 = (-6 (-1) (-3))/2:
(-6-1 (-3))/2
(-6)/2 = (2 (-3))/2 = -3:
--3 (-3)
-3 (-1) = 3:
3 (-3)
3 (-3) = -9:
Answer: -9
It is irrational. Otherwise sqrt(2) would be rational too which is not true.
C is 3/5. D is 1. B is underlined
