Hello:
<span>A= { 15, 25, 35, 45, 55, 65 } and B= { 25, 45, 65}
</span> A∪B = <span>{15, 25, 35, 45, 55, 65 } ....(answer : d )</span>
Answer:
5c+4=2(c-5)
opening the parentheses we get:
5c+4=2c-10
putting like terms together we get
5c-2c=-10-4
3c=-14
c=-14/3
so the answer would be A. C = - 4 2/3
Y=5^x when x is 2.
y=5^2
y=25
Hope this helps!
