not really

The area of a playground is 216 yd^2. The width of the playground is 6 yd longer than its length. Find the length and width of t

zvonat [6]

Let the length of the playground be x, then the width is 6 + x.

Area = length * width = x * (6 + x) = 6x + x^2 = 216

Solving the quadratic equation x^2 + 6x - 216 = 0, we have x = 12 or -18

i.e length = 12 and width = 6 + 18 = 18

Simplify the expression <br> y^12/y^12

andreev551 [17]

Step-by-step explanation:

________________________________

Step 1:

$\frac{{y}^{12} }{ {y}^{12} }$

Wright the equation

________________________________

Step 2:

${y}^{12 - 12}$

Transfer the power of y ie ¹² up to subtract it

________________________________

Step 3:

${y}^{0}$

by subtracting the powers we get 0

________________________________

Step 4:

$1$

so the results comes 1 because anything ⁰=1

Madelyn has x nickels and y dimes, having a maximum of 15 coins worth no

Answer:

2 nickels, 9 dimes

Step-by-step explanation:

When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the <em>unshaded</em> area the solution space. Here, the vertices of the triangular solution space are ...

(2, 9), (2, 13), (6, 9)

Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.

Three solutions are shown:

(x, y) = (2, 9), (3, 10), (4, 11)
