Your answer is c, common sense
Answer:
34.2 or 34.20
Step-by-step explanation:
Sometimes they accept 34.2 without the zero, but that's up to you

To solve this equation , we need to write it in quadratic form

To get the equation in quadratic form we replace x^2 with u

can be written as
, Replace u for x^2
So equation becomes

Now we factor the left hand side
-16 and -1 are the two factors whose product is +16 and sum is -17
(u-16) (u-1) = 0
u -16 = 0 so u=16
u-1 =0 so u=1
WE assume u = x^2, Now we replace u with x^2
Now take square root on both sides , x= +4 and x=-4
Now take square root on both sides , x= +1 and x=-1
So zeros of the function are -4, -1, 1, 4
7x^4 +7/x^2 on the interval [-2,3]
The answer is d, when you divide 45 by 54 you get 0.833333333333.... the line above the 3 means that there is infinite number of threes
