Answer:
A.
Step-by-step explanation:
Answer:
±5sqrt(6)/6 = m
Step-by-step explanation:
4/9 = m^2-1/54
Add 1/54 to both sides
4/9+ 1/54 = m^2-1/54 +1/54
4/9+ 1/54 = m^2
Get a common denominator of 54
4/9 *6/6 + 1/54 = m^2
24/54 + 1/54 = m^2
25/54 = m^2
Take the square root of each side
±sqrt(25/54) = sqrt(m^2)
±sqrt(25/54) = m
±sqrt(25)/sqrt(54) = m
±sqrt(25)/sqrt(9)sqrt(6) = m
±5/3sqrt(6) = m
±5/3sqrt(6) *sqrt(6)/sqrt(6) = m
±5sqrt(6)/3*6 = m
±5sqrt(6)/6 = m

I don't know either
Step-by-step explanation:
Answer:
-8x^2-10x+12
Step-by-step explanation:
first set up the problem:
(-3x^2-7x+5)-(5x^2+3x-7)
Since you are subtracting you need to distribute the (-) sign:
(-3x^2‐7x+5)(-5x^2-3x+7)
Now just combine like terms
-3x^2+(-5x^2= -8x^2
(-7x+(-3x= -10x
5+7= 12
set answer in standard form:
-8x^2-10x+12
