Answer 29.
The product of two nonzero integers will be less than or equal to both of the integers if they are multiplied by number itself and one or by number itself and one with negative sign.
Answer 30.
The sign of the product of three integers with the same sign will be positive or negative. If odd number of same sign is multiplied, the product will be of that sign.
(+) (+) (+) = (+)
(-) (-) (-) = (-)
15. s = 10 because in a 45-45-90 degree triangle the longer and shorter leg have the same distance, r = 10√2 because the hypotenuse in a 45-45-90 degree triangle is √2 times the same variable as the longer and shorter leg
16. n °= 30° because it is a 30-60-90 triangle I knew that it was 30 degrees, 2n° = 60° because variable n equals 30 degrees and two times 30 equals 60, q = 15√3 I followed the formula of a 30-60-90 degree triangle that states the longer leg is equal to √3 times the shorter leg, p = 15 I got this answer because the hypotenuse (which is 30) is two times the shorter leg so all I had to do was divide by two to get 15 (the shorter leg)
17. Couldn't see got cut off.
18. c = 12 I saw that the square was made up of 4 congruent triangles and I noticed that one triangle had its hypotenuse given. I noticed that this triangle was a 30-60-90 degree triangle so I took 24 (the hypotenuse) and divided it by two to get 12 because the hypotenuse is two times the shorter leg. Next I looked at where variable c was and since all the triangles are congruent I saw that It was the shorter leg and I took the 12 that I found in the former triangle to get the answer c = 12.<span>
