Answer:
5(3x + 5) or 15x + 25
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +5)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 25
Answer:c
Step-by-step explanation: By graph, it is clear that the closest time for lunch is 1:40pm as she spent more time in hiking after a constant time.
The equation of the line is y= 3 - 2x.
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given:
Coordinates (0, 3) and (2, -1)
So,
slope = -4/2=-2
and equation of line is
(y- y1) = m (x- x1)
y-3 = (-2)(x-0)
y-3 = -2x
y= 3 - 2x
Hence, the equation of line is y= 3 - 2x.

Answer:
Coordinates of the point on the directed line segment is (15/3,7/3)
Step-by-step explanation:
Given:
A line segment with coordinates partition in some ratio.
Lets say that the ends of the segment are A and B.
We have to find the coordinates of C.
Coordinates of point A are = (3,-1)
Coordinates of point B are = (9,8)
Considering the point C as (x,y) and the partition ratios as m:n i.e 1:2
