A box is to be made from a rectangular piece of corrugated​ cardboard, where the length is 8 more inches than the​ width, by cut
Ksenya-84 [330]
The volume of a box like this is found by multiplying the length times the width times the height.  We are told that the length is 8 more inches than the width, so the width is w and the length is w + 8.  If we cut away 3 square inches from each corner, the height when we fold up those corners is going to be 3.  The volume is given as 27, so our formula looks like this:  27=(3)(w)(w+8).  When we do that multiplication, we have  27=3w^2+24w.  We need to solve for w so we can then solve for h.  Move the 27 over and set the quadratic equal to 0.  3w^2+24w-27=0.  We can then factor out a 3 to make the job easier:  3(w^2+8w-9)=0.  Now we can factor to solve for w.  The 2 numbers that add up to 8 and multiply to -9 are 9 and -1.  So (w+9) = 0, (w-1) = 0, or 3 = 0.  Of course 3 doesn't equal 0, so that's out.  w + 9 = 0 so w = -9.  w - 1 = 0 so w = 1.  There are 2 things in math that can never EVER be negative and those are time and distance/length.  So -9 is out.  That means that w = 1.  But don't forget that there was 6 inches cut off each side, so the width is 1 + 3 + 3 which is 7.  The length is w + 8 which means that the length is 7 + 8 or 15.  Those are the dimensions of the rectangle before it was cut.

The larger of two numbers is twice the smaller increased by five. Find the two numbers if three times the larger exceeds double
melomori [17]

Answer:

Larger number is 13 and Smaller number is 4.

Step-by-step explanation:

Let the larger number be x.

Also let the smaller number be y.

We need to find the two numbers.

Given:

The larger of two numbers is twice the smaller increased by five.

framing in equation form we get;

x=2y+5 ⇒equation 1

Also Given:

Three times the larger exceeds double the smaller by 31

3x=2y+31 ⇒equation 2

Now Substituting the value of x from equation 1 in equation 2 we get;

3(2y+5) = 2y+31

Now Using Distributive property we get;

6y+15 = 2y +31

Combining the like terms we get;

6y-2y = 31-15

Now Using Subtraction property we get;

4y =16

Now Using Division property we get;

\frac{4y}{4}=\frac{16}{4}\\\\y =4

Now Substituting value of y in equation 1 we will find the value of x.

x=2y+5\\\\x = 2\times4+5\\\\x=8+5\\\\x=13

Hence Larger number is 13 and Smaller number is 4.
