896 is your answer. All you would have to do is round the 28 up to 30 then do 3×32. After that you would put a 0 at the end of your answer because you took off the 0 when you did 3×32. After that you would take away 2×30 because you rounded the 28 to 30 too make it easier. After you do that this will be what your equation will look like: 28×30= [(30×32)-(2×30)]=896 This method is called Partial Product

The function A = 15x - x2, where x is the width in yards, gives the area A of a llama pen in square yards. Make a table using 1/

Answer:

The width which gives the greatest area is 7.5 yd

Step-by-step explanation:

This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen

Answer:

30 ft²

Step-by-step explanation:

Area of trapezium = 1/2 (a + b)h

a = 6 ft , b = 9 ft , h = 4 ft

Area = 1/2 (6 + 9) 4

= 30 ft²
