Answer:
13.9 or 14
Step-by-step explanation:
a^2 + b^2 = c^2
5^2 + 13^2 = c^2
25 + 169 = 197
square root 197 to get c
c = 13.9 (14 rounded up)
Helpful thing to note is that the hyptoenuse will always be longer than your "long side" of the triangle
12x+3x+1 = 15x+1
8r+2+2+-3 = 8r+1
8p+7-p+1 = 7p+8
4xy+17+14xy-xy = 17xy+17
11+4-2b+8b = 15+6b
Did the best I could.
16
7:4
7 * 4 = 28
4 * 4 = 16
