Triangle question:
If you know that the perimeter is 6x, then (x+3)+(2x+4)+?=6x, as perimeter is a measure of the sum of all the sides. So we already have 3x+7+?=6x, now we need to add another 3x and get rid of the 7, this can simply be written as 3x-7, which will be the expression for the missing side. We can check this - 
x+3+2x+4+3x-7= 6x

Rectangle question:
We know that in rectangles, two pairs of sides are equal. So, the length opposite the 3x-3 is also 3x-3. Now, we know what perimeter is and the unique trait about the sides of a rectangle so the equation looks like this - 
6x-6+2(?)=10x+6
Solve for x as follows:
6x-6+2(?)=10x+6
Step 1: Minus 6x on both sides
-6+2(?)=4x+6
Step 2: Add 6 on both sides
2(?)=4x+12
Step 3: Divide both sides by 2
?=2x+6
We can check if this is correct - 
3x-3+3x-3+2x+6+2x+6=10x+6

Answer:

15

Step-by-step explanation:

When you find the sum of 3 and 5 you get 8, which represents the total number of vehicles used in the trucks to cars ratio.

This means that the ratio of cars to total vehicles in this ratio is 5 to 8. Because there are 24 vehicles in the parking lot, and 8 × 3 = 24, you can multiply the entire ratio by three to get your answer:

5 to 8 ⇒ 15 to 24

Therefore, the number of cars in the parking lot is 15.

Simplity 2(- 4)+7(x + 2).
Evgesh-ka [11]

Answer:

Step-by-step explanation:

To find your answer you first have to multiply the numbers that aren’t in parentheses and you multiply 2 and 7 and you get 14 then you  don’t have to worry about the x because it is a variable so now add  -4 +2. but first we have to turn negative into positive so you add -4 + 8
