(2x + 5) \times( x - 2) \\  = 2x(x) + 2x( - 2) + 5(x) + 5( - 2) \\  = 2 {x}^{2}  + ( - 4x) + 5x + ( - 10) \\  = 2 {x}^{2}  - 4x + 5x - 10 \\  = 2 {x}^{2}  + x - 10
The answer is 2x^2 + x - 10

Daredevil Danny was cliff jumping. He jumped off a cliff that was 1 4 . 2 14.214, point, 2 meters above the surface of the water
iragen [17]

<em>Question:</em>

<em>Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the  water. At the end of his jump, Danny was 2.3 meters below the surface of the water. </em>

<em>The following equation describes this situation  14.2 + (-16,5) = -2.3 .</em>

<em>What does -16.5 tell us?</em>

<em></em>

Answer:

The displacement between his current position and his initial position

Step-by-step explanation:

Given

Initial\ Position = 14.2m

Final\ Position = -2.3m

14.2 + (-16.5) = -2.3

Required

What does -16.5 represents?

<em>To understand this, we need to first calculate the displacement between his initial and final position</em>

<em></em>

Displacement = Final\ Position - Initial\ Position

Displacement = -2.3m - 14.2m

Displacement = - 16.5m

<em>So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)</em>

Shania wants to purchase a book bag with an original price of $28. 0. She also bought a necklace for $35. 75. There is a storewi
omeli [17]
Answer:
$24.36 for the bookbag if they tax the original price
$23.97 if they tax the sales price
$31.10 for the necklace if they tax the original price
$30.60 if they tax the sales price

So an overall of $55.46 was spent for a taxing of the original price and an overall of $54.57 was spent for the taxing of the sales price.

Step-by-step explanation:
20% of $28.00 is $6.60, subtract $6.60 from $28.00 and you'll get $22.40.
7% of $28.00 is $1.96, add $1.96 to $22.40 and you'll get $24.36 (for taxing of the original price). If you want the taxing of the sales price then you'd do 7% of 22.40 which is $1.57, add that to $22.40 and you get $23.97

Then you do the same for the necklace:
20% of $35.75 is $7.15, subtract $7.15 from $35.75 and you'll get $28.60.
7% of $35.75 is $2.50, add $2.50 to $28.60 and you'll get $31.10 (for taxing of the original price). If you want the taxing of the sales price then you'd do 7% of 28.60 which is $2.00, add that to $28.60 and you get $30.60
Add the final numbers and you'll get your overall.

Hope this helps
