Not entirely sure about the equation, but hes 4. 4 plus 11 is 15, fifteen plus 5 is 20. (fifteen is five less than 20) and 20 is 5 times his age, which is 4
Answer:
B C and F
Step-by-step explanation:
Polygons are closed shaped with straight lines
D and E have curves therefore they cannot be classified as polygons
A is not closed therefore it A is not a polygon
B, C and F are closed and use only straight lines therefore those 3 are polygons
Subtract 8x from both sides and then divide both sides by 11 making the equation y=8/11x+8. First, you go up 8 places on the y intercept and make a point. From there, go up 8 (rise) points and right 11 (run) because the slope is 8/11 and it is rise/run.
Answer: The length of the bottom left side is 14.
To find the length of this side, we need to know the relationship between the different sections when chords cross each other.
The relationship is that if you multiply the 2 parts of each chord together, it will equal the product of the two sides in the other chord.
Our equation can be written as:
7(8) = 4(x)
56 = 4x
14 = x
