Answer:
3. 33
4. g(x) = 3 (1+n)
Step-by-step explanation:
For the equation, I am not entirely sure that is what your teacher is looking for, but it definitely works! : )
To make it I just said that it looked like there were three different equal parts to the figures, and the area of the parts increases by one every time. So I just added 1 to whatever number it is which gets the area of one of the parts, and multiplied it by 3!
For number 3, I just plugged it into the equation I just made.
g(x) = 3(1+(10))
= 3(11)
= 33
The area of a triangle is half that of the square around it, so in this case that would be:
The formula for the volume is:
This leads to:
Answer:
Step-by-step explanation:
First find circumference of circle: C=2r = 18.84
Rectangle area = 18X13 = 244.92
Area of circles is (pi)r^2 = 28.6
244.92+28.6+28.6 = 302
Well, first of all, you have to open up the bracket by multiplying what's outside by what's inside. Anyway;
3k-15=-16
Next, you have to collect the like terms and put them together. And the -15 becomes +15. So;
3k=-16+15
3k=-1
Next, you have to divide the both sides by 3. So;
3k/3=-1/3
k=-1/3
So your answer is -1/3. Hope i helped. Have a nice day.
