Answer:
21,600
Step-by-step explanation:
Answer: y-12
Step-by-step explanation:
-3(y+4)+4y
first distribute teh -3 to the y and the 4, so you get -3y and -12. Then combine like terms. -3y-12+4y, add the -3y and 4y, you get y. So the answer is y-12.
11^2x11^2=x^2
121+121=x^2
242=x^2
Radical 242 = radical x^2
Full solved answer is 15.56
Step-by-step explanation:
g(f(x)) = f(x) substituted in g(x)'s function.
g(3x^2 - x - 8) = 3x^2 - x - 8 + 5 = 3x^2 - x - 3.
For x^2-49
this is a diffarence of two perfect squares. I suggest that this is memorised.
a^2-b^2=(a-b)(a+b)
so x^2-7^2=(x-7)(x+7)
so to solve x^2+x-56 you want to find out what two numbers add to 1 and multiply to make -56
since -56 is negative we know that the two number are difarent signs so that eliminatess answers B and D.
if we try answer C -8+7=-1 so the answer is not C because we want +1 not -1
then we see that 8+(-7)=1 so the answer is A
