(а+1) (а+2)-(а+1)(а-2)-а-1

umka21 [38]

If you would like to calculate (a + 1) * (a + 2) - (a + 1) * (a - 2) - a - 1, you can do this using the following steps:

(a + 1) * (a + 2) - (a + 1) * (a - 2) - a - 1 = a^2 + 2 * a + 1 * a + 2 - (a^2 - 2 * a + 1 * a - 2) - a - 1 = a^2 + 3 * a + 2 - a^2 + 2 * a - 1 * a + 2 - a - 1 = 3 * a + 3

The correct result would be 3 * a + 3.

Timothy bought 10 cookies for $5.00 let x represent the number of cookies purchased and let y represent the total cost. graph th

Soloha48 [4]

We are given that cost of 10 cookies = $5.

Let us find the cost of one cookie.

Cost of one cookie = 5/10 = $0.5.

Let us assume number of cookies purchased = x cookies.

And total cost of x number of cookies = y.

Therefore,

Cost of x cookies at the rate $0.5 each cookie = 0.5x

Therefore, cost equation would be

y=0.5x.

For 0 number of cookies there would be 0 cost.

So, first coordinate would be (0,0) and we are given 10 cookies cost = $5.00.

Therefore, second coordinate would be (10,5).

Plotting (0,0) and (10,5) coordinates on the graph and jointing the points to draw a line.

The drawn line represents the proportional relationship.
