Answer:
1 + 1 · 7 + 1 · 72 + . . . 1 · 76
Step-by-step explanation:
bc
By graphing the given points, you will see that a rectangle can be made from the points. Points A and B lie on the same line horizontally as well as points C and D. To determine the distance between points, we use the distance formula expressed as:
d = √((y2-y1)^2 + (x2-x1)^2)
For points A and B, the term (y2-y1)^2 is equal to zero since they lie on the x-axis. The formula would become
d = √(x2-x1)^2
d = x2-x1 = a - 0 = a
Therefore, the distance would be equal to the value of a.

Answer:
D. –X+XY–7y
Step-by-step explanation:
We just have to combine (add) the similar terms... so all terms that have an x in them for example.
–3x + 2xy + 4y – xy + 2x – 11y
Let's first re-write it placing similar terms next to each other
(-3x + 2x) + (2xy - xy) + (4y - 11y)
Then we sum them up, for each similar terms
1x + 1xy -7y
so, x + xy -7y
Answer D.
Answer:
Add 22/63
Step-by-step explanation:
3/7 + n = 7/9
<u>Step 1: Subtract 3/7 from both sides</u>
3/7 + n - 3/7 = 7/9 - 3/7
n = 49/63 - 27/63
n = 22/63
Answer: Add 22/63
