<h3>
Answer: C) -48x^7y^3 </h3>
Explanation:
The coefficients are -8 and 6, which are to the left of the variable expressions. The coefficients multiply to -48. Based on this alone, the answer is between choice C or choice D.
For the variables, we add the exponents. The x terms multiply to x^5*x^2 = x^(5+2) = x^7
The y terms multiply to y^2*y = y^2*y^1 = y^(2+1) = y^3
Putting everything together, we end up with -48x^7y^3
There are 64 handshake because eaxh hand is shaked 8btimes and there are 8 people, so 8×8=64
<u>Answer:</u>
f (x, y) = 40x + 25y
<u>Step-by-step explanation:</u>
We are given that Efficient Homemakers Ltd. makes canvas wallets and leather wallets as their project.
Assuming to be the number of leather wallets and to be the number of canvas wallets, we are to write a function showing their total profit for both wallets.
Profit on canvas wallet () = $25
Profit on leather wallet () = $40
<u>Total profit from both wallets:</u>
f (x, y) = 40x + 25y
Answer:
c i think
Step-by-step explanation:
Let the original number be ‘x’
Then half of that number= 1/2x or simply x/2
Similarly one fifth of that number = x/5
According to the question
x+x/2+x/5=51
Taking LCM
10x/10+2x/10+5x/10=51
Multiplying 10 throughout
10x+2x+5x=510
17x=510
x=510/17
Therefore x=30
