Answer:
20
Step-by-step explanation:
We know that the formula for the area of something is 1/2 * base * height
So we multiply 1/2 * 8 * 2 for The first triangle and get 8
Repeat for the other 3:
1/2* 2*2 = 2
8+8+2+2 = 20
* there are 4 triangles but I only needed to do the formula for two of them because they have identical triangles.
I hope this helps :)

Answer:
x=6
Step-by-step explanation:
First, add 1 on both sides
4x + 5 = 5x -1
+1 +1
4x+6 =5x
Then, subtract 4x on both sides
4x+6 =5x
-4x -4x
6=x
So, x equals 6
Hope this helps! :)
Answer: the store paid $18.3 for the sweater
Step-by-step explanation:
Let x represent the amount that the store paid for the sweater.
A store marks up the price of a sweater by $7.35. This means that the new or current price of the sweater at the store would be
7.35 + x
The total cost of the sweater is 25.65. Therefore, an equation to represent the problem would be
7.35 + x = 25.65
Subtracting 7.35 from the left hand side and the right hand side of the equation, it becomes
7.35 + x - 7.35 = 25.65 - 7.35
x = $18.3
The answer is 45 degrease
