When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.

9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
26/24=x/10
26*100=x*24 (cross multiply)
2,600=34x (divide)
x=76.47
therefore 26 is 34% of 76.47
Answer:6 i think
Step-by-step explanation:
Ivan will need 24 cans. 56/10 = 5.6. Each can is 5.6 cm tall. 162.4-28 =134.4
134.4/5.6 = 24
Its 2,4 as the correct answer
