Answer:
B) 103.25
Step-by-step explanation:
Area of rectangle:
A = bh
A = (16)(4)
A = 64
Area of a semi-circle:
r = d/2 = 5
A = (πr²)/2
A = (3.14 * 5²)/2
A = (3.14 * 25)/2
A = (78.5)/2
A = 39.25
Combined:
64 + 39.25 = 103.25
Add 9 to both sides
So
33=2x
Divide both sides by 2
So
X=16.5
Hey there!
A number that is divisible by both 2 and 9 is 18. This is just 2 multiplied by 9. To make this into a 3-digit number, you can just multiply 18 by itself. This will be 324, which is divisible by 9 and 2.
324 ÷ 2 = 162
324 ÷ 9 = 36
So, a number you could choose is 324.
Hope this helped you out! :-)
2 + 4(3+2x) = 3x + 8
2 + 12 + 8x = 3x + 8
14 - 8 = 3x - 8x
6 = -5x
x = -6/5
