<h3>Answer:  (2x-y)(2x+y)</h3>

===========================================

Work Shown:

4x^2 - y^2

(2x)^2 - (y)^2

(2x-y)(2x+y)

When going from the second step to the third step, I used the difference of squares rule. That rule is a^2-b^2 = (a-b)(a+b). In this case, a = 2x and b = y.

Side note: (2x-y)(2x+y) is the same as (2x+y)(2x-y). We can multiply in any order.

Sonny run 4.5 km everyday. One day after he ran 2.5 km, he felt very sick. He walked 0.3 meters before a friend gave him a ride
MAXImum [283]

2 km

4.5km - 2.5km = 2km. The 0.3m is negligible unless it means kilometers. If it is indeed kilometers, it is 1.7km.

Stella [2.4K]

Answer:

Abby's mother spent $9.75 for the classroom not including tax.

Step-by-step explanation:

Know:

5 bags for 1 dollar

10 candy bars for 50 cents

3 whistles for 75 cents

5×6=30

10×3=30

3×10=30

  1. 5 times 6 is thirty. So find the product of 6 and 1 which is 6. 6 is the overall cost of bags.
  2. 10 times 3 is 30. So find the product of 3 and .50 which is 1.50. 1.50 dollars is the overall cost of candy bars.
  3. 3 times 10 is 30. You then find the product of 3 and .75. The product of this is 2.25 which is the total cost of whistles.
  4. Next you add all the values together which are 6.00 + 1.50 + 2.25 this equals $9.75
