Brian just bought 9 bags of 14 cookies each. He already had 8 cookies in a jar. How many cookies does Brian have now?
RUDIKE [14]

Answer: 134 cookies

Step-by-step explanation: First we want to find the total amount of cookies Brain bought. Simply multiply 14 x 9 to find the total amount of cookies bought.

14 x 9 = 126 cookies.

Since Brian already had 8 cookies in the jar, we will simply add the new amount of cookies he bought to the cookies in the jar left.

126 + 8 = 134 total cookies that Brain has now.

Suppose the length and width of the box double. Does the surface area S double? Complete the explanation.
dezoksy [38]
Answer is NO, it does not double.

Step by step.

Equation for surface area (SA) = 2lw+2lh+2wh

If we double the length and width, making them each 2l and 2w, we then have:

2(2l x 2w) + 2(2l x h) + 2(2w x h)
= 2(4lw) + 4lh + 4wh
SA = 8lw + 4lh + 4wh

If the surface area had been doubled, we should get the equation (4lw + 4lh + 4wh) for a doubled surface area.

So no, it is not doubled.
