What are we supposed to be doing
Answer:
12ft
Step-by-step explanation:
(5x²+4x-80)(x²-5x-24)=5x²(x²-5x-24)+4x(x²-5x-24)-80(x²-5x-24)
{distributive property of multiplication}
=5x^4-25x³-120x²+4x³-20x²-96x-80x²+400x+1920
=5x^4-21x³-220x²+304x+1920
This is the answer.
<em>- 8n + 9</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>A - B = ( -3n + 2 ) - (5n - 7)</em>
<em>= - 3n + 2 - 5n + 7</em>
<em>= - 8n + 9</em>
<em>Good luck !</em>
The value of r is found as 3/2 such that line that passes through the pair of points.
<h3>Describe the term slope of the line?</h3>
- The ratio of both the altitude to that same horizontal distance (rise across run) between two places is typically used to calculate the slope, a numerical value that represents how steep a line is.
- A line's slope provides information on the steepness and direction of the line.
- By calculating the difference between coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of either a straight line between them.
- The letter "m" is frequently used to denote slope.
The slope is given bye the equation;
m = (y2 - y1)/(x2 - x1)
For the given question, the points are given as;
(x1, y1) = (r, -5),
(x2, y2) = (3, 13)
m = 8
8 = (13 + 5)/(3 - r)
8(3 - r) = 18
8r = 6
r = 3/2
Thus, the value of r is found as 3/2 such that line that passes through the pair of points.

The correct question is-
Find the value of r so the line that passes through each pair of points has the given slope. (r, -5), (3, 13), m = 8
