!!!!!!!!50 POINTS!!!!!!!!!!!!Suppose a square has a side length by the expression x+5/8x. What is the perimeter of the square?

Answers

This is equal to (x -5)(x - 5), or (x - 5)².
Therefore, using the formula given above, the side's length is equal to (x - 5).

Muliply that by four to obtain the perimeter.

4(x - 5) = 4x -20.

For the second problem, disregard the brackets since there are no other operations besides subtraction and addition.

So it would become 3x^4 -x + 2 + 9x^5 - x² + x.

Now simplify everything and rewrite it in decreasing terms of power,

9x^5 + 3x^4 - x² + 2.

Answers

Answer: The slope is 2 -Please mark brainliest

1. Find the X and Y values of each point

X1: 1

X2: -1

Y1: 3

Y2: -1

2. Subtract X1 from X2 and Y1 from Y2

Y: -1-3=-4

X: -1-1=-2

3. Divide the X value by the Y value

-4/-2=2

The slope of the line shown on the coordinate plane is 2.

Answer:

Step-by-step explanation:

(X1,Y1)=(1,3)

(X2,y2)=(-1,-1)

slope(m)=y2-y1/x2-x1

= -1-3/-1-1

= -4/-2

= 2
