Answer:
$57.63
Step-by-step explanation:
For x > 3, the price in dollars Mr. Roshan will pay for x pounds of beef is ...
cost = 4.99×3 +4.49(x -3) = 3(4.99 -4.49) +4.49x
cost = 1.50 +4.49x
Then for x = 12.5 pounds, the cost is ...
cost = 1.50 +4.49×12.5 = 1.50 +56.13
cost = 57.63
Mr. Roshan will pay $57.63 for 12.5 pounds of beef.

Answer: 576 </h3>
============================================================
Check out the diagram below.
I've split the figure into 3 separate blocks. We calculate the volume of each block, then add up those volumes to get the final answer.
- Block A = largest block on the left
- Block B = middle block
- Block C = smallest block on the right
So,
- volume of block A = length*width*height = 6*6*8 = 288 ft^3
- volume of block B = length*width*height = 6*6*5 = 180 ft^3
- volume of block C = length*width*height = 6*6*3 = 108 ft^3
Therefore, the total volume we're working with is:
A+B+C = 288+180+108 = 576 cubic feet
The "cubic feet" or "ft^3" portion is already taken care of by your teacher, so you just need to type in the number itself.
<span>I think you meant 6x²+13x-5 so first thing we have to do is factor it which is really quite tricky with this kind of trinomial so first take ac which is 6 times -5 so -30 now figure out factors of -30 that will add up to 13 how about 15 and -2 now that we have the factors write the equation again</span>
<span /><span> 6x²+15x-2x-5 </span>split the equation in half<span />
<span>6x²+15x -2x-5 so out of the first equation we can pull a 3x out</span>
<span>3x(2x+5) and out of the second we can pull a negative 1</span>
<span>3x(2x+5) -1(2x+5) rewrite it</span>
<span>(3x-1)(2x+5) so the 3x-1 is the factor we already had so the other side is (2x+5)</span>
