2 positive integers is the answer to this question because if you test the hypothesis, for example lets take 1 and 2 for instance. |1+2| = |1| + |2|  3=3. Whereas if you tried other hypothesis' they would not work. So, 2 positive integers is the answer.

Kin made a Picture frame for a square picture with sides that are 5f-4 inches long. Framing the picture adds 2 inches to the len
elena-s [515]

The perimeter of a shape is the sum of its side lengths

The expressions for the perimeter of the frame are 4(l + 2) and 4l + 8

<h3>How to determine the perimeter of the shape</h3>

The side length of the frame is given as l

So, the perimeter of the frame is

:P = 4l

When 2 inches are added to each length, the perimeter of the frame becomes

P =4(l + 2)

Expand

P =4l + 8

Hence, the expressions for the perimeter of the frame are 4(l + 2) and 4l + 8

Which term best describes a proof in which you assume the opposite of what u want to prove​
ANTONII [103]

Answer:

The Latin phrase is "reduction ad absurd um", meaning reduction to absurdity. You assume the opposite and show that logically it leads to a contradiction and therefore cannot be true.

Hope this helps.

Bob and Mark talk about their families. Bob says he has 3 kids, the product of their ages is 72. He gives another clue: the sum
Damm [24]
Not this riddle again


3 kids
what you are supposed to do is factor 72 and see their sums
1+1+72=74
1+2+36=39
1+3+24=28
1+4+18=23
2+2+18=22
1+6+12=19
2+3+12=17
1+8+9=18
2+4+9=15
2+6+6=14
3+3+8=14
3+4+6=13


notice that all the sums are different except for the 2 that add to 14
since there is not enough info, we can conclude that the sum was 14 and that the ages is either 2,6,6 or 3,3,8
after he says, "the youngest is called justice"
now we know there is a youngest
it cannot be 3,3,8 because 3 and 3 are both youngest
therefor the ages are
2,6 and 6 years old
