Answer: 3
Step-by-step explanation: Use the pythagorean theory!!!
a^{2} +4^{2}=5^{2}
a^{2}=5^{2}-4^{2}
a^{2} =25-16
a^{2}=8 square root both sides √
a=2.8=3
2x + 2
6(x - 3) - 4(x - 5)
6*x - 6*3 - 4*x - 4 * -5
6x - 18 - 4x + 20
if u is an irrational number added to a rational number (sqrt 15) to yield 2, then that would mean u would = root -1.78.....
which means you wouldn't have a real solution. if you want a complex answer, it would be sqrt(1.78)i
16
3 x 4 = 12
4 x 4 = 16
