The sum of the polynomials (8x²-9y²-4x)+(x²-3y²<span>-7x) is:
1. You must add the terms whose variables and exponents are the same.
2. Let's rewrite the polynomials:
</span>
(8x²-9y²-4x)+(x²-3y²-7x)
8x²-9y²-4x+x²-3y²-7x
(8+1)x²+(-4-7)x+(-9-3)y²
3. Therefore, the result is:
9x²-11x-12y²
3. <span>What is the sum of the polynomials?
The answer is: </span>9x²-11x-12y²
Answer:
a = 24
r = 1/2
<h3>8th term = ar^(n-1)</h3><h3> = 24. (1/2)^-1/2</h3>
Answer:
Je pense que je ne sais pas vraiment
There are 18 packets.
Each packet has 10 cookies.
Let T = total number of cookies.
T = 10(18)
T = 180
There are 180 cookies.
Let C = cost of each cookie.
Use the equation C = 19.80/T.
You know what T is, right? Look above to see the value of T. Plug that T-value into the equation and solve for C.
After that, round your answer as instructed.
