What do you need help with?
Step-by-step explanation:
2x^2+6x=36
x^2+3x=12
x^2+3x-12=0
x=(-3+(57)^0.5)/2 or x=(-3-(57)^0.5)/2
Answer:
Option c. integers from 1 to 10 inclusive.
Step-by-step explanation:
The given sets are A = { 1, 3, 5, 7, 9 }
B = { 2, 4, 6, 8, 10 }
C = { 1, 5, 6, 7, 9 }
We have to determine A ∪ B
A ∪ B = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }
Therefore, A ∪ B is the set of all from 1 to 10 inclusive.
option C will be the answer.

Answer:
<h2>
36.48 mm^2</h2>
Step-by-step explanation:
The area formula of a circle is:
A=pi*r^2
a semicircle is half the area of a circle:
A=0.5*pi*r^2
now lets find that area:
A=0.5*pi*r^2
A=0.5*pi*8^2
A=0.5*pi*64
A=<u>32pi </u>mm^2
A= around 32*3.14
A= around 100.48 mm^2
Now, lets find the area of the triangle:
it is half the product of the diameter and radius:
A=0.5*8*(8+8)
A=4*16
A=64 mm^2
Now lets find the approximate area of the shaded region:
Asc-At=Ashaded
Ashaded=100.48-64
Ashaded=36.48 mm^2
