Answer:
xy + 5x
Step-by-step explanation:
collect the like terms:
xy+3x+2x (add 3x and 2x together)
xy + 5x
Answer:
90
x 3 multiply the 3 and the 0, and get 0, then the 9 and 3 and get 27
-------
270

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
<span>Instead of k, k+1, k+2, you should use k, k+2, k+4 with the constraint that k is even (i.e. if you return an odd integer for k, or a non-integer, then return no solution).
</span><span>k + (k+2) + (k+4) = 4k
</span><span>3k + 6 = 4k
k = 6
</span><span>Indeed, 6+8+10 = 4*6.</span>
So for 4, first thing you need is slope. Choose 2 points. I am choosing (8,2) and (6,3) So, then its the second y term subtracted by the first y term over(Or divided by) the second x term subtracted by the first x term.
3-2/6-8 or 1/-2 or -.5 (negative 0.5)
Now, time to find the yintercept(yint). So, choose one of the points, Im choosing (8,2), and put it into slope intercept, but leave yint as b.
(2)=-.5(8)+b
simplify
2= -4+b
subtract -4
b=6
So, your answer is y= -0.5x+6
