Well, negatives are less than zero, and the greater the number the less it is, or in this case colder, so we know that the first two are -19, and -10, then comes 0, and increases from there. So, the answer would be B. (-19, -10, 0, 15, 28)

-8-8x^2=-31<br> how to solve for x

Zepler [3.9K]

Answer:

x = ± $\sqrt{\frac{23}{2\sqrt{2}}}$

Step-by-step explanation:

-8 - 8x^2= -31

Since this is a quadratic, it needs to be factored.

First, move the x to the other side:

-8 = 8x^2 - 31

Then, get the x alone by first adding 31:

23 = 8x^2

then dividing by 8:

x^2 = 23/8

Finally, square root both sides and remember the even roots property:

x = ± $\sqrt{\frac{23}{8}}$

and simplify the root 8:

x = ± $\sqrt{\frac{23}{2\sqrt{2}}}$

Note: This answer may have a mistake.

A fruit stand has 5 bags of apples with 8 apples in each bag if there are 3 more aples on the shelf next to the bags how many to

trapecia [35]

Answer:

Step-by-step explanation:

So if there are 5 bags which each have 8 apples in them and we need to find out how many apples there are all we have to do is multiply 8 x 5 = 40

But there are 3 more apples off to the side so we just take 40 and add 3 to it.

40 + 3 = 43
