How can you predict whether the sum of two integers is 0, positive, or negative?

zepelin [54]

Answer:

See explanation:

Step-by-step explanation:

Let a and b be integers.

Sum means addition.

So we are trying to figure out what a+b equals.

It could result in as 0, negative, or positive.

a+b is 0 when a and b are of opposite values. Example: 5+(-5) or -5+5 is 0 because 5 and -5 are opposite values.

a+b is positive when both a and b are positive. Example 5+3=5.

a+b is positive when |a|>|b| and a is positive. Example: 5+(-3)=2 since |5|>|-3| and 5 is positive.

a+b is positive when |a|<|b| and b is positive. Example: -3+5=2 since |-3|<|5| and 5 is positive.

a+b is negative when both a and b are negative. Example: -5+(-3)=-8.

a+b is negative when |a|>|b| and a is negative. Example: -5+3=-2 since |-5|>|3| and -5 is negative.

a+b is negative when |a|<|b| and b is negative. Example: 3+(-5)=-2 since |3|<|-5| and -5 is negative.

Find the missing side lenghts

nevsk [136]

You first have to use Pythagorean Theorem to find the side lengths of the triangle with the hypotenuse of 10. The side lengths are 5sqrt2.
Now do Pythagorean theorem again to find the side length is 5

I'm confused on simplifying radicals.

lakkis [162]

Answer: 4 or $\sqrt{4 * 4}$

To find the square root of a number, remember that there will be two factors that are the same that will give you the product.

Lets start from 1:

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 x 4 = 16

As you can see, 4 x 4 is 16. To make sure I'm correct, remember that a square roots consists two identical factors.

4 and 4 are the same numbers.

Therefore, $\sqrt{16}$ = 4

It can also be written as $\sqrt{4 * 4}$

Latoya has b decks of cards . Each deck has 52 cards in it , what is the expression for the total numbers of cards latoya has

Lerok [7]

Answer:

52b

Step-by-step explanation:

She has 52 cards per deck, and b decks.

This means she has 52b cards.

How this works:

For 1 deck, she has 52 cards, or 52×1 cards.

For 2 decks, she has 104 cards, or 52×1 cards.

For 5 decks, she has 260 cards, or 52×5 cards.

For 10 decks, she has 520 cards, or 52×10 cards.

Therefore, for b decks, she has 52×b, or 52b cards.
