<span>The best answer is C.add 2 to both sides of the equation.
</span>5=x-2
5+2=x-2+2
7=x-0
x=7
The answer would be 8. I got that by adding up all the numbers (64) and then dividing <span>how many numbers there are total which gave me the answer of 8.</span>
Use pythagorean theorem
c2 = a2 + b2
c2 = 1.5^2 + 2^2
c2 = 2.25 + 4
c2 = 6.25
c = 2.5
Where is the triangles ???
