Answer:

**Answer:**

x^2+9x -8

**Step-by-step explanation:**

(12x^2+8x-3)-(11x^2-x+5)

12x^2+8x-3-11x^2+x-5

x^2+9x -8

Answer:

**Answer:**

x^2 + 9x - 8

**Step-by-step explanation:**

Break the brackets out and you will get:

(12x^2+8x-3)-(11x^2-x+5)

= 12x^2 + 8x -3 - 11x^2 - (-x) - (+5)

= 12x^2 + 8x - 3 - 11x^2 + x - 5

=12x^2 - 11x^2 + 8x + x - 5 - 3

= x^2 + 9x - 8 or x(x+9) -8

You can factorize it even more but it won't factorize much so you can keep it as this equation!

Lee sold **60 **magazine

**Step-by-step explanation:**

Terrence and Lee were selling magazines for a charity

- In the first week, Terrance sold 30% more than Lee
- In the second week, Terrance sold 12 magazines, but Lee did not sell any
- Terrance sold 50% more than Lee by the end of the second week

We need to find how many magazines Lee sold

Assume that Lee sold x magazines

∵ Terrance sold 30% more than Lee in the first week

∵ Lee sold x magazines in the first week

- Find 30% of x and add it to x to find how many magazines

Terrance sold

∵ Terrance sold = 30% × x + x

∴ Terrance sold = × x + x = 0.3 x + x

∴ Terrance sold = 1.3 x magazines in the first week

∵ Terrance sold 12 magazines in the second week

- Add 1.3 x to 12 to find the number of magazines that Terrence

sold in the two weeks

∴ Terrence sold 1.3 x + 12 magazines in the two weeks

∵ Lee did not sell any in the next week

∴ Lee sold x magazines in the two weeks

∵ Terrance sold 50% more than Lee by the end of the 2nd week

- Equate 1.3 x + 12 by the sum of x and 50% of x

∴ 1.3 x + 12 = 50% × x + x

∵ 50% × x = × x = 0.5 x

∴ 1.3 x + 12 = 0.5 x + x

- Add the like terms in the right hand side

∴ **1.3 x + 12 = 1.5 x**

- Subtract 1.3 x from both sides

∴ 12 = 0.2 x

- Divide both sides by 0.2

∴ **60 = x**

**Lee sold 60 magazine**

It is still 3 units, because you just moved it.

87 nickels because 5 times 87 is going to equal to 435

Easy, you have 435 cents

1 nickle= 5 cents

435/5=87

Thus, you have collected 87 nickles.

1 nickle= 5 cents

435/5=87

Thus, you have collected 87 nickles.

**Step-by-step explanation:**

Lets first simplify the dimensions of the rectangle

length = 7

breadth = = = 0.6

The area of rectangle = length * breadth

so, area of rectangle = 7 * 0.6

**Area of rectangle = 4.2**

Hope it helped you.. :D

length = 7

breadth = = = 0.6

The area of rectangle = length * breadth

so, area of rectangle = 7 * 0.6
