Answer: 14
Step-by-step explanation:
21-7=14
Answer: b
Step-by-step explanation:
x=12
12+5=17
3 times 12 is 36+10=46
46+17=63
12+51=63
They are both 63
using pythagorean theorem
a^2 + b^2 =c^2
a^2 +8^2 =14^2
a^2 +64 = 196
subtract 64 from each side
a^2 = 132
take the square root of each side
a^2 = sqrt (132)
a=11.48912529
a =11.5
