Answer:
2nd one
Step-by-step explanation:
Taking into account the repeated ones it would be 7! what is 7*6*5*4*3*2*1
The whole ends up being 42 ft².
Area of a triangle = 1/2 * base * height.
So that lil triangle piece is 1/2 * 2 * 3 = 1/2 * 6 = 3
Now we do the rectangle piece. Area of a rectangle = length * width
So that rectangle is 3 * 7 = 21
If you take away those two, you are left with a trapezoid.
Area of a trapezoid is 1/2 * (base 1 + base 2) * height
Base 1 is the width of the rectangle which is 3. Base 2 is the 6. The height is the given 11 feet minus the 7 feet from the length of the rectangle which is 4.
Plug all this in to the formula you get 1/2 * (6 + 3) * 4 = 1/2 * 9 * 4 = 1/2 * 36 = 18.
Now add all of your areas together;
21 + 3 + 18 = 24 + 18 = 42
Answer:
x=5
Step-by-step explanation:
distribute first
2(-4x+3)
-8x+6
-8x+6+3x+3=-16
combine like terms
then get the variable alone
-5x+9=-16
-9. -9
<u>-5x</u><u>=</u><u>-25</u>
-5. -5
x=5
