Answer: A
Steps:
12(8+x)=126
96+ 8x=126
-96 -96
8x= 30
x=3.75
Ummm the answer is c 63 times 5
Answer:
18 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 2880°, thus
180° (n - 2) = 2880 ( divide both sides by 180 )
n - 2 = 16 ( add 2 to both sides )
n = 18
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
