Answer: 6p^3+29p^2+22p-21
8 ft wide, 12 ft long......so if u want it 2 ft wide, u have a scale factor of 1/4.
that means ur length will be 12 * 1/4 = 12/4 = 3 ft long
A = L * W
A = 3 * 2
A = 6 square ft <==
Okay, so slope intercept form is y=mx+b. Like a normal problem with numbers, you add or subtract from each side.
3x-2y= -16
you want to leave the y by itsself, so your going to add 3x to 16, but write it out how the formula is (y=mx+b). now, you should have -2y= -3x-16. (the three is now negative because you moved it to the other side of the equation.)
now, remember that you want the y all by itself, so, all you have to do now is divide.
-2y= -3x-16 ---------- now is y= -3/-2x minus 16/-2. (those are now fractions, but the y is alone.) now you simplify.
-3/-2x is already simplified, but 16/-2 is not so it changes into -8,after dividing the fraction.
now you have the answer.
y= -3/2x-8x (it is the same as the formula now!)
hope this helps! it was hard to explain through typing but if you read it carefully, i explained every step.
To solve this, you can set up an equation. Make the length of the shortest side x, so the 2 sides double the length will equal 2x. Since they all equal the perimeter of 36, do x + 2x + 2x =36. These values all represent the sides(2 longer, one short). Combine like terms to get 5x=36 then divide by 5 to find the value of x. x=7.2in meaning the shorter side is 7.2 inches while the longer sides are both 14.4 inches each since they are double in size.
Hi
Here is the solution.
To find how much sand is in each bag we have to divide the weight of the sand by number bags.
Each bag hold = 48/12 = 4 pounds.
That's the answer.
