15 x 1 because there's not really any multiples that equal 15
To find the mean, you must add all of the value and then divide by how many there were so
(9+12+10+8+11+12+13+6)/8
81/8
10.125 inches
Answer:
hypotenuse
Step-by-step explanation:
It states that a2 + b2 = c2 for the sides of any right triangle (c is the hypotenuse, or longest side), AND it also states that if the three sides of a triangle obey this formula, they do form a right triangle. Since 6 is the longest sides, it would have to be the hypotenuse.
<u>Statement </u> <u>Reason</u>
1. AB = x + 16 1. Given
BC = 4x + 11
AC = 77
2. AB + BC = AC 2. Segment Addition Postulate
3. x + 16 + 4x + 11 = 77 3. Substitution Property
4. 5x + 27 = 77 4. Simplification <em>(added like terms)</em>
5. 5x = 50 5. Subtraction Property of Equality
6. x = 10 6. Division Property of Equality
7. AB = 10 + 16 7. Substitution Property
8. AB = 26 8. Simplification <em>(added like terms)</em>
