The value you should get is 34. I'm assuming n is variable we should use. "the square of a number increased by 9" = "n^2+9" in an algebraic expression. then you plug in. 5^2+9 and then solve. 5^2=25. 25+9=34
Answer:
2⁹
Step-by-step explanation:
Using the rule of Indices:
aⁿ x aˣ = aⁿ⁺ˣ
Hence: 2²⁺³⁺⁴
= 2⁹
In a year she will have 1290$ because if she gets paid every 2 months and there are 12 months, 12/2 equals 6 times she gets paid a year. So 215 times 6 is 1290
If it’s only 1.4x + 3.5y then that’s the answer because you can’t do anything with them. Since one has an x variable and the other has a y variable you can’t combine them together.
