Answer:

2(x - 3)

Step-by-step explanation:

Like terms;

5x and -3x are like terms

-8 and +2 are like terms

So, combining like terms

(5x - 3x) + (-8 +2)

2x - 6

Which is simplified further to;

2(x - 3)

Hope this helps,

if you have any part of the process I didn't answer that you're confused on please leave me a comment and I'll respond with further explanation

A and B are two points on square ABCD with coordinates A(1,3) and B(5,3). What are the lengths of the diagonals AC and BD? Round
lilavasa [31]

Answer:

AC = BD = 5.7

Step-by-step explanation:

Given

A = (1,3)

B = (5,3)

Required

The length of the diagonals

First, calculate the length of AB using:

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}

So, we have:

AB = \sqrt{(1 - 5)^2 + (3 - 3)^2}

AB = \sqrt{(-4)^2 + 0^2}

AB = \sqrt{16}

AB = 4

The diagonal of a square is calculated using:

Diagonal = x\sqrt{2

Where x is the length of each side.

So:

AC = BD = AB\sqrt{2}

AC = BD = 4\sqrt{2}

AC = BD = 5.7 -- approximated
