Answer:

  20

Step-by-step explanation:

The sides of the 4-sided figure are the same length, so we can find the perimeter (sum of side lengths) by multiplying one side length by 4.

<h3>Side length</h3>

Points F(-2, -2) and G(-2, 3) lie on the same vertical line: x = -2. The distance between them is the difference of their y-coordinates:

  FG = (3 -(-2)) = 5

Each side is 5 units long.

<h3>Perimeter</h3>

The length of the four sides is ...

  P = 4s = 4(5) = 20

The perimeter of the rhombus is 20 units.

Answer:

y=3/4x-2

Step-by-step explanation:

y=mx+b

the b is the y-intercept so find the y-intercept of the line:

which is -2

the slope you need to find two points and look how many times do you need to rise or run to get the answer: 3/4

Hope this helps!

What is the least common denominator of 9,8,6,5
Alex

Answer:

1

Step-by-step explanation:

LCD = 1

Equivalent Fractions with the LCD

9 = 9/1

8 = 8/1

6 = 6/1

5 = 5/1

Solution:

Rewriting input as fractions if necessary:

9/1, 8/1, 6/1, 5/1

For the denominators (1, 1, 1, 1) the least common multiple (LCM) is 1.

LCM(1, 1, 1, 1)

Therefore, the least common denominator (LCD) is 1.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

9 = 9/1 × 1/1 = 9/1

8 = 8/1 × 1/1 = 8/1

6 = 6/1 × 1/1 = 6/1

5 = 5/1 × 1/1 = 5/1

Please help algebra 1 question
vlada-n [284]

Answer:<u> x=-3</u>

<u></u>

Step-by-step explanation:

2x(3x+9)=-2(2x+6)

2/3 (3x)+2/3(9)=(-2)(2x)+(-2)(6) distrubute this

2x+6=-4x+-12

2x+6=-4x-12.    subtract 4 on both sides

2x+6=-4x-12

2x+6+4x=-4x-12+4x

6x+6=-12

6x+6-6=-12-6

6x=-18

6x/6=-18/6

=x=-3

Hoped this helped sorry it took me forever:)
