It is prime because it has no common factors in 5a^2 and b.
The answer is
A<span>

Just use the Pythagorean Theorem
(9 +x)^2 = 15^2 + x^2
x^2 + 18x + 81 = 225 + x^2
18x = 144
x = 8
So the three sides of the triangle are
15, 8 and 17
C -3/2
Just multiply the second equation by -3/2
this will make the y term = -3/4y
so adding will eliminate the y terms.

Answer:
C
Step-by-step explanation:
193b=212.3
193b/193=212.3/193
(divide by 193 to get the value of b)
193 cancels 193
b= 1.098445596
(round off to one decimal place)
b=1.1
