The area of a triangle is 1/2 bh
so to find the area of the larger triangle do the following calculation:
1/2 time 12 time 7. that will give you 42 ft squared. that is the larger triangle.
the next way to find the area i will show you is:
pretend that the the triangle is inside of a rectangle. now you have 4 triangles. you know that the base of the rectangle is 15 ft anf the height is 7. now take the smaller triangle and it has its rectangle base 3 and height 7. multiply to get 21 feet squared. divide by 2 since there are 2 triangles in the small rectangle. 10.5 feet squared
If x=first even number in sequence, then the next even number would be that number plus 2, plus 4, and so on.
x + (x+2) + (x+4) + (x+6) + (x+8) = 100
5x+20=100
5x=80
x=16
Step-by-step help:
399 - 75 = 324.
Now that we have the bonus out of the equation, the fraction is approximately
324/12.
Divide by 2,
162/6
Divide by 2 again,
81/3.
81 divided by 3 is 27.
So,
The answer is exactly 27.
Hope that helped!
I think maybe the first or second number line.
The inequality can be simplified to -5 ≤ x < 3, so the solution set is:
[-5, 3)

How to solve the inequality for x?</h3>
I assume that the inequality is something like:
-4 ≤ 2*x + 6 < 12
To solve this for x, we need to isolate the variable in one of the parts of the inequality.
To do that, we can perform the same operation in the 3 sides.
If first we subtract 6 in all the sieds of the inequality we get:
-4 - 6 ≤ 2*x + 6 - 6 < 12 - 6
-10 ≤ 2*x < 6
Now we can divide by 2, so we get:
-10/2 ≤ 2*x/2 < 6/2
-5 ≤ x < 3
So we can conclude that the solution set of that inequality is [-5, 3)
