4a²=144
a²=144/4
a²=36
a=⁺₋√36
a=⁺₋6
Answer: we have two values for a; a=-6; and a=6
we check it out:
if a=-6
4(-6)²=4*36=144
if a=6
4(6)²=4*36=144
602.88cm(to the third power but there is no exponent on keyboard)
Answer:
5.52 or less
Step-by-step explanation:
The total cost must be less than or equal to the budget amount
Total cost limit ≥ fee + cost per ticket * number of tickets
542.94 ≥ 45.82 + cost per ticket * 90
Subtract 45.82 from each side
542.94 - 45.82≥ 45.82 -45.82+ cost per ticket * 90
497.12 ≥ cost per ticket * 90
Divide each side by 90
497.12≥cost per ticket * 90
497.12/90≥ cost per ticket * 90/90
5.52 ≥ cost per ticket
