Answer:
7 should be the answer. on the calculator I got 7.26 but you need the simplified answer
Answer:
Inverse property of addition.
The name of the shape is an octagon. Since there are 9 identical tiles and you have 72 sides, you would divide 72 by 9 and get 8. And shape that has 8 sides would be an octagon.
Answer:
Parallel lines have the same slope. Because the functions \displaystyle f\left(x\right)=2x+3f(x)=2x+3 and \displaystyle j\left(x\right)=2x - 6j(x)=2x−6 each have a slope of 2, they represent parallel lines. Perpendicular lines have negative reciprocal slopes. Because −2 and \displaystyle \frac{1}{2}

are negative reciprocals, the equations, \displaystyle g\left(x\right)=\frac{1}{2}x - 4g(x)=

x−4 and \displaystyle h\left(x\right)=-2x+2h(x)=−2x+2 represent perpendicular lines.
