Answer:
<u>364 cm²</u>
Step-by-step explanation:
Area of the figure :
- Area (triangle) + Area (rectangle 1) + Area (rectangle 2) + Area (rectangle 3)
- 1/2 x 20 x 14 + 12 x 9 + 7 x 3 + 19 x 5
- 140 + 108 + 21 + 95
- 248 + 21 + 95
- 269 + 95
- <u>364 cm²</u>
The volume a cylinder is v=(area of base)h and since the area of the base is πr², you can write the equation a v=πr²h. Since the problem wants us to find what be is in the equation of a cylinder as v=Bh, we know that B=πr². The problem gave us the diameter of the circle so we no the radius is going to be the diameter (24) divided by 2 which equals 12. therefore B=12²π.

Factoring the polynomial
by grouping means separation of the polynomial in two addends, each of them consists of two addends:
In first brackets the common factor is
in second brackets the common factor is 
Then

Answer: correct choice is B
11x + 4y = 18
3x + 4y = 2.....multiply by -1
----------------
11x + 4y = 18
-3x - 4y = -2 (result of multiplying by -1)
---------------add
8x = 16
x = 16/8
x = 2
3x + 4y = 2
3(2) + 4y = 2
6 + 4y = 2
4y = 2 - 6
4y = -4
y = -4/4
y = -1
solution is : (2,-1)
