Answer:

Step-by-step explanation:
Multiply 5*3 to get 15, and each x and y is squared, so 5xy needs another set of x and y to have two xs and ys in the final expression, so you multiply
by
to get your answer.

Answer: Divide the total displacement by the total time.
In order to find the velocity of the moving object, you will need to divide the change in position by the change in time. Specify the direction moved, and you have the average velocity. Example 1 (cont.): The car changed its position by 36 meters over 8 seconds.
Answer:
Step-by-step explanation:
Discount = 20% of 129.99

= $26
Price after discount = 129.99 - 26 = $103.99
Tax = 8.5% of 103.99

= $8.84
Selling price including tax = 103.99 + 8.84
= $112.83
Amount saved = 129.99 - 112.83
=$ 17.16
Answer:
x = 3
Step-by-step explanation:
Since the triangles are congruent then corresponding sides are equal, thus
x - y = x + 2 ( subtract x from both sides )
- y = 2 ( multiply both sides by - 1 )
y = - 2
and
4x + 2y = 2x - y
substitute y = - 2
4x - 4 = 2x + 2 ( subtract 2x from both sides )
2x - 4 = 2 ( add 4 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
