Answer:
-5
Step-by-step explanation:
3x²y + xy²
Let x = -1/2 and y = 4
3(-1/2)^2 (4) + (-1/2) (4)^2
Exponents first
3(1/4) (4) + (-1/2) 16
Multiply
3 - 8
Subtract
-5
0.084 is the answer because 0.84 divided by 10 is 0.084
Of course A does because integers are positive and negative
Answer:
16
Step-by-step explanation:
To solve this question,we will have to understand some symbols in mathematics...
For example,* means ×
/ Means÷
We have so many of them
So back to the question
2*2^3 means 2 multiply by 2 raise to the power of 3
So 2^3 is 8
Therefore,2*8 means 2×8
It equals to 16
Therefore the final answer is 16
I hope you understand it better now
