Answer:

-4(x-4)²+9y(y+4)=0

Step-by-step explanation:

If we put the -64 with the x’s instead of the y’s, we get:

-4x²+32x-64+9y²+36y=0

-4(x²-8x+16)+9y(y+4)=0

-4(x-4)²+9y(y+4)=0

Write <br> 9<br> 5<br> as a mixed number.
Advocard [28]
<span>Well, think of it this way? How many times does 5 go into 9? 

5 * 1 = 5 
5 * 2 = 10 

So 5 goes into 9 one time. Then you have to subtract that 5 from 9 to be left with your fraction value. 

1 and 4/5 is your mixed number.</span>

The computation shows that the thickness of the beam is 3.75 inches.

<h3>How to calculate the values?</h3>

11. The thickness of the beam will be:

= 3/4 inch × 5

= 3.75 inches.

12. The length of the board will be:

= 7 5/8 × 5

= 38.125 inches.

13. The total height of the stairs will be:

= 8 3/16 × 13

= 106.4375 inches.

14. The height of the stack will be:

= 55 × 3/8in

= 20.625 inches.

15. The length of the board will be:

= 3/4 × 86 1/4

= 64.6875 inches.

16. The number of hours that it'll take to replace the trim will be:

= 37 1/2 × 1/4

= 9.375 hours.

17. The height of the will required will be:

= 22 × 5/12

= 9.167 feet

18. The inches removed from the wood will be:

= 1/16 × 7

= 0.4375 inches.

19. The shortest finish stock will be:

= 3/16 × 15

= 2.8125 feet.

20. The total amount of board wasted will be:

= 3/16 × 11

= 2.0625 inches.

solong [7]

9514 1404 393

Answer:

  • 5 mph
  • 50 miles

Step-by-step explanation:

To find miles per hour, divide miles by hours:

__

To find distance, multiply speed by time.

Please help <br><br>must show work<br><br><br>there are 5 that I'm stuck on​
Cloud [144]

you cannot show too much "work"

basically, you remove what is common to all of the factors, and then put brackets, as it will be multiplied back in, remember that when you multiply exponents with the same base, its same as adding them, so subtract to remove...

you can seperate two of the variables , then factor, then subtract the last one from those two, because it cannot be factored out , as in part2 #2
