Area = base * height. This is because you can move the triangle on the left to the right side, forming a rectangle, which has an area of base * height.
For this shape, the area is 2.8m * 6.2m = 17.36 m^2. I don't see that answer listed, nor are the answers in m^2, which is strange.
10 - 5(2/3)
10 - 3(1/3)
20/3 is your final answer
Thus is how you write y=2x-7 in a function notation. ANSWER:F(x)=2x-7.
Answer = 5 problems per minute
Because you do the number of problems divided by the minutes eg 35/7 = 5
