Answer:

(6y+17)

Step-by-step explanation:

1. Subtract 4y from 10y to get 6y

2. 9 is positive and 8 is negative but to subtract a negative is basically adding so you would add 9 to 8

3. You final equation would be (6y+17)

4. (10y+9)-(4y-8)= (6y+17)

Calculate the area of the following shape. full answer/explanation please
DerKrebs [107]
To find the area of this entire shape, we must divide it into two rectangles.

The first rectangle is on the bottom of the shape, with a length of 8 cm and a width of 3 cm.

The second rectangle is on the top of the shape. The length is (8-5) cm and the height is (7-3) cm.

To find the area of the total shape, we must add the areas of the two rectangles. To find the area of the rectangle, we use the formula, A = l * w.

8 * 3 = 24 cm^2
3 * 4 = 12 cm^2

24 sq cm + 12 sq cm = 36 square centimeters.

Therefore, the area is 36 square centimeters. Hope this helps! :)

5 + 4 + 6 = 15

Find favourable outcomes:

5

The probability for drawing a red marble is:

5/15 or 1/3

Multiply this ×3 to find the probability of drawing three red marbles.

1/3 × 1/3 × 1/3 = 1/27

1 ÷ 27 = 0.0370370370 ... repeating
