Question:
What is 3(x + 2) - 2(x + 1)?
Steps:
When you solve this type of equation always use the distributive property formula to solve this equation!
Formula: a(b + c) = ab + ac
So, what is 3(x + 2) ?
Also, what is -2(x + 1)?
Then, put it back into the equation for you to solve this problem.
So, this would be the new equation:
3x + 6 - 2x - 2
Then, what you want to do is put variables next to each other and the numbers next to each other so it will be easier to simplify:
3x - 2x + 6 - 2
Then, simplify:
x + 4 is the answer!
Since 3x - 2x = x and 6 - 2 = 4

Well you start by dividing 19779 by 20820 to see the percent of people compared to last year (it being 95%). Then you take 19,779 and multiply it by the same percentage, or 0.95. That means that there should be 18790 (it's technically 18790.1 but since that's people you round to the nearest whole number).
The little lines in each side show that the sides are the same length but you also need to find the length of the smaller side which isn’t the same. For this imagine that the shape is split into a square and a triangle and you need to find the long side of the triangle using Pythagoras
a^2 + b^2 = c^2
20^2 + 20^2 = 800
Square root of 800 = 28.3
Then do 28.3-20=8.3
So I think the answer is 20+20+20+20+20+8.3=108.3 cm
Answer:
x = -2
Step-by-step explanation:
10x+8=3x-6
subtract 10x-3x
7x+8= -6
subtract -6-8
7x=-14
divide 7 into -14
x = -2
Hope this helps!
