1) Find the total area of the shape.
2) Determine the value of 'L'. Area = 40.
3) Determine which choice best shows the distributive property of multiplication. A. 1 x 4 = 4 B. 4 x (3 x 7) = (4 x 3) x 7 C. 4 x (3 + 7) = (4 x 3) + (4 x 7) D. 4 x 3 = 3 x 4
4) Determine which choice best shows the identity property of multiplication. A. 2 x 5 = 5 x 2 B. 1 x 2 = 2 C. 2 x (5 + 10) = (2 x 5) + (2 x 10) D. 2 x (5 x 10) = (2 x 5) x 10
5) Determine which choice best shows the associative property of multiplication. A. 2 x (9 x 0) = (2 x 9) x 0 B. 2 x 9 = 9 x 2 C. 1 x 2 = 2 D. 2 x (9 + 0) = (2 x 9) + (2 x 0)
6) Determine which choice best shows the commutative property of multiplication. A. 1 x 10 = 10 B. 10 x (5 x 9) = (10 x 5) x 9 C. 10 x 5 = 5 x 10 D. 10 x (5 + 9) = (10 x 5) + (10 x 9)
7) Use <, >, or = to compare the numbers. 784 ___ 541
8) Use <, >, or = to compare the numbers. 322 ___ 300
9) 229 + 624 = B
10) 297 = 835 - B
A pet store sold 7 kittens and 1 puppy over the weekend. Write an equation to show how many animals were sold.

Answer

  1. The total area of the shape is calculated by adding the areas of the two rectangles: (2 x 5) + (7 x 4) = 10 + 28 = 38 square units.

  2. To find the value of 'L', use the formula for the area of a rectangle: 8 x L = 40. Solving for L gives L = 40 / 8 = 5.

  3. The distributive property of multiplication is shown by: C. 4 x (3 + 7) = (4 x 3) + (4 x 7).

  4. The identity property of multiplication is shown by: B. 1 x 2 = 2.

  5. The associative property of multiplication is shown by: A. 2 x (9 x 0) = (2 x 9) x 0.

  6. The commutative property of multiplication is shown by: C. 10 x 5 = 5 x 10.

  7. 784 is greater than 541, so the comparison is: 784 > 541.

  8. 322 is greater than 300, so the comparison is: 322 > 300.

  9. 229 + 624 = 853, so B = 853.

  10. 297 = 835 - B, solving for B gives B = 835 - 297 = 538.

  11. The equation to show how many animals were sold is: 7 + 1 = 8.
