Answer:
29
Explanation:
Let John be x years old.
Michael is <span>x+17</span> years old.
In four years time, the sum of their ages will be 49:
<span>x+x+17+2<span>(4)</span>=49</span>
<span>2x=24</span>
<span>x=12</span>
So Michael is <span>12+17=29</span> years old now.
Answer:
Each angle is equal to 108 degrees. The internal angles of a pentagon add up to 540.
No matter what the side lengths are, so long as it is a regular pentagon, each angle will always be exactly 108 degrees.

Answer:
So we have x+3 if -3<=x<=-1
and 5 if -1<=x<=1
Step-by-step explanation:
The one piece from -1 to 1 is horizontal so the line is in the form of y=a number. It goes through 5 on the y-axis so the equation there is y=5.
From -3 to -1, that is a line with positive slope (since that part is increasing).
Slope=rise/run
We see from the filled in dot to the unfilled in dot that the rise is 2 and the run is 2 so the slope is 2/2=1.
So if we did extend this line where we go at on the y-axis? It would go through 3 because starting from the unfilled dot and rising 1 and running 1 will get us to the 3 on the y-axis.
The equation of a line in slope-intercept form is y=mx+b.
We have m=1 and b=3 so the equation is y=1x+3 or just y=x+3.
So we have x+3 if -3<=x<=-1
and 5 if -1<=x<=1
