12. Consider the general rational equation a/b=c/d
velikii [3]

Part (a)

Answer:  ad = bc

-------------------------

Explanation:

In the equation a/b = c/d, we have b and d in the denominator.

If we multiply both sides by bd, then the denominators will cancel. The expression bd is the same as bd/1.

As a similar example, consider the equation

a/b = 12

if we multiply both sides by b, then we clear out the denominator to end up with a = 12b

As another example, let's consider

a/b = c

Multiplying both sides by b leads to

a = bc

The same idea applies with the denominator d as well.

When going from a/b = c/d to ad = bc, your textbook may refer to this process as "cross multiplication".

=================================================

Part (b)

Answer:  bd is the product of the denominators

-------------------------

Explanation:

Often in math, writing two variables next to each other represents multiplication.

bd is the same as b*d which means "b times d". The term "product" is the result of multiplying two or more values.

b and d are both in the denominator of each fraction, so bd represents the product of the denominators.

fourth,sixth and thirteenth term in this sequence A(n)= 6+(n+1)(-2) help me to find and describe the explicite formula
OleMash [197]
Hello,

A(n)=6+(n+1)^(-2)=6+1/(n+1)²

A_{4} =6+ \dfrac{1}{(4+1)^2} =6+ \dfrac{1}{25}= \dfrac{151}{25} \\&#10;&#10; A_{6} =6+ \dfrac{1}{(6+1)^2} =6+ \dfrac{1}{49}= \dfrac{295}{49} \\&#10;&#10; A_{13} =6+ \dfrac{1}{(13+1)^2} =6+ \dfrac{1}{196}= \dfrac{1177}{196} \\&#10;

Permitter question!! giving points!!
kompoz [17]

Answer:

2L + 2W = 88

L = W + 12

L = 28 feet & W = 16 feet

Step-by-step explanation:

2L + 2W = 88

[] The perimeter of a rectangle is length + length + width + width, shortned as 2(legnth) + 2(width) and since the perimeter of the garden is 88, this option works.

L = W + 12

[] The length is 12 feet longer than the width, so the width + 12 will equal the length

Solving:

{ 2L + 2W = 88

{ L = W + 12

[Plug-in] 2(W + 12) + 2W = 88

[Distribute] 2W + 24 + 2W = 88

[Combine like terms] 4W + 24 = 88

[Subtract 24 from both sides] 4W = 64

[Divide both sides by 4] W = 16

L = W + 12 -> L = (16) + 12 -> L = 28
