Surface area is the area of the faces added together.
First lets find the area of one of the triangles.
Area of triangle is 1/2*base*hight
Area=1/2*2*3= 3
Area of ONE tringle is 3, and area of the FOUR tringles is 4*3 whihc is 12
Now lets find area of square
area of square is side*side
So, area is 2*2 which is 4
Now lets add area of triangles+area of square
12+4 which 16
Surface area is 16
Answer:
A. 20 inches
Step-by-step explanation:
Answer:
(-∞,-4)
Step-by-step explanation:
1. Move like terms together
-4x + 18 ≤ - 2 -9x
Move -9x, the sign changes to a positive
-4x + 18 +9x ≤ -2
Move 18, the sign changes to a negative
-4x + 9x ≤ - 2 -18
2. Combine like terms
-4x+9x becomes 5x
-2-18 becomes -20
The new equation is 5x≤-20
3. Divide both sides by 5
5x÷5=x
-20÷5=-4
x≤-4
4. Write in interval notation
Answer:
A
Step-by-step explanation:
The point slope form of the equation is where m is the slope and is a point on the line.
First find the slope by subtracting two points from the line.
To write the equation substitute in:
The answer is A.
Answer:
396
Step-by-step explanation:
If you find the multiples of each number the smallest number they have in common is 396.
44 * 9 = 396
36 * 11 = 396
Hope this helps!
