Answer:
3
Step-by-step explanation:
Break the problem up into two
Ignore the -1 for now
2+2=4 because if you separate 2 and 2, you get four ones, therefore it's four
Now that you have four, subtract 1
And you got 3
(16x^2+4x-4x-1)-3=15x^2
16x^2-1-3=15x^2
16x^2-4=15x^2
X^2=4
X=+or-2
Answer:
781/1680
Step-by-step explanation:
Don't you have a calculator?
I assume that by (1 2/3 1/9), you mean (1+2/3)*(1/9)
Assuming that you put all necessary parentheses:
781/1680, approx. 0.4648809523809524
