So basically the perimeter of a parallelogram is

2*length + 2*width

Or, in this case, once you substitute everything in,

2 * (3x + 9) + 2 * (4x - 5)

Use the distributive property, to distribute the 2s to everything inside the parenthesis.

2 * 3x + 2 * 9 + 2 * 4x + 2 * -5

6x + 18 + 8x - 10

Then just add everything

14x + 8 = perimeter

Six less than x<br>I'm in 8th ​
Fudgin [204]

Answer

I found this. Does this help?

Step-by-step explanation:

If this is an inequality (6 is less than x, or 6 < x), then x is an integer or other value greater than 6.

The variable statement "6 less than x" is (x - 6)

This is a value (variable and constant) where the value of x is determined by an equation

such as x-6 = 4 (x is positive 2) or y = x-6 (y is 6 less than x).

A race car game takes 6 points from a player each time the player hits a cone. What integer represents the change in total point
Helga [31]

Given:

A race car game takes 6 points from a player each time the player hits a cone.

To find:

The integer which represents the change in total points if the player hits 10 cones.

Solution:

According to the given information,

1 hit = -6 points

Here, negative sign represents the reduction in points after hitting a cone.

If the player hits 10 cones.

(1 × 10) hit = (-6 × 10) points

10 hit = -60 points

So, the change in total points if the player hits 10 cones is -60.

Therefore, the required integer is -60.
