butalik [34]3 years ago

Answer:

x = -8.

Step-by-step explanation:

Now combine the x terms.  We get x - 3y = 136 and 18x + 3y = -288.

Combining these two equations eliminates the y terms, leaving us with:

19x = -152.  Solving for x, we get:  x = -8.  This corresponds to the second answer choice.

An open box is made from a 20 cm x 3 cm piece of tin by cutting a square from each corner and folding up the edges. The area of
Marta_Voda [28]

Answer:

Length of the final sides: 6 cm and 16 cm

Step-by-step explanation:

The lengths of the sides of the original box are

L=20 cm\\W=10 cm

Later, a piece of tin is cut out from each corner; the piece cut out has the shape of the square: we can call the length of its generic side x. Therefore, the dimensions of the box will now be:

L'=L-2x\\W'=W-2x

We also know that the area is

A=96 cm^2

And the area can be written as product of length and width, therefore:

A=L'W'

So we find:

A=(L-2x)(W-2x)\\96=(20-2x)(10-2x)

Solving for x,

96=200-20x-40x+4x^2\\4x^2-60x+104=0\\\\x^2-15x-26=0

Which has two solutions:

x = 13 cm (this is larger than the initial length of the width, therefore we discard it)

x = 2 cm

So, the length of the new sides are

L=20-2x=20-2(2)=16 cm\\W=10-2x=10-2(2)=6 cm

Dimensional Analysis Method (also called conversion factor or unit analysis) (Appendix D: Dimensional Analysis, Page 397) o The
garik1379 [7]

Answer:

The dimensional analysis method uses equivalences written in <u>fractional</u> form. Because the numerator and denominator of the fraction are equivalent, the value of the fraction is <u>1.</u> Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label). In order for units to cancel they must be in <u>the numerator and the denominator</u> of the fraction

Step-by-step explanation:

Dimensional analysis is a method of problem solving that takes into consideration the identity property of multiplication whereby the product of a number and 1 will always give the same number, that is 1 × n = n whereby the value "n" remains the same after the multiplication

Therefore, a fraction of two equivalent measurements but different units has a value of 1, and multiplying the equivalent fraction with another measurement with the same unit as the denominator of the fraction with a value of 1 changes the unit to that of the unit of the numerator
