2 times (9+7) is correct.
9 + 7 = 16.
16 multiplied by 2 is 32.
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Since a pentagon has 5 sides, you would divide the perimeter by the number of sides.
641.5/5 = 128.3cm
Therefore, the length of one side of the pentagon is 128.3cm.
She practiced 630 hours in all because you multiply 18x35
Slope formula is y2-y1/x2-x1.
Using this, we can say that -3 – 2/5 – 0=
1.
