Answer:

\frac{x+7}{x-3}

Step-by-step explanation:

When you factor each equation, you result in two of the factors canceling out, resulting in \frac{x+7}{x-3}.

[Top Equation]

The middle number is 3 and the last number is -28.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 3

Multiply together to get -28

Can you think of the two numbers?

Try -4 and 7:

-4+7 = 3

-4*7 = -28

Fill in the blanks in

(x+_)(x+_)

with -4 and 7 to get...

(x-4)(x+7)

[Bottom Equation]

The middle number is -7 and the last number is 12.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -7

Multiply together to get 12

Can you think of the two numbers?

Try -3 and -4:

-3+-4 = -7

-3*-4 = 12

Fill in the blanks in

(x+_)(x+_)

with -3 and -4 to get...

(x-3)(x-4)

At a certain time of day, a 5.5 foot tall man has a 6 foot shadow. if a tree is 19.25 feet tall, what is the length of the shado
Minchanka [31]
At a certain time of day, a 5.5 foot tall man has a 6 foot shadow. if a tree is 19.25 feet tall, what is the length of the shadow of the tree(x=shadow of the tree)

the equation for the problem is...
5.5/6=19.25/x
you then multiply the denominators on both sides...
5.5x=19.25*6
you then solve on one side...
5.5x=115.5
and then divide 5.5 on both sides to leave x alone...
x=21
the shadow of the tree is 21
