Change the following mixed expressions to fractions and then simplify the complex fractions.

Answers

Answer:

[tex]\frac{3(a-7)}{4x(a-4)}[/tex]

Step-by-step explanation:

One is given the following expression:

[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]

The most logical first step to solve this equation is to factor it. Rewrite each quadratic equation as the product of two linear equations. Unfortunately, no additional explanation can be provided. To prove that the product of the two linear terms are the factors of the quadratic term, one must distribute and simplify,

[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]

[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]

Now simplify this expression, then cancel common terms in the numerator and denominator,

[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]

[tex]\frac{9x^2(2a+5)(a-7)}{12x^3(2a+5)(a-4)}[/tex]

[tex]\frac{3(a-7)}{4x(a-4)}[/tex]

I believe the answer would be
3(9-7)
4x(a=4)

Let,
The first triangle with sides 7 and 3.5 be ΔABC
The second triangle with sides 3 and x be ΔCDE

ΔABC ≅ ΔCDE (they are congruent) as:
1) They have a common point C
2) ∠ABC = ∠CDE = 90° (given)

Hence we can say,

AC/CE = BC/CD

= 7/x = 3.5/3

Therefore,
x = (7*3)/3.5
= 21/3.5

The total amount needed is $165 if your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip. This is 1/3 of the money needed for the trip.

Let x be the total amount needed:

A linear equation in one variable can be framed as follows:

1/3 of x = 55

x/3 = 55

x = 55x3

x = $165

Thus, the total amount needed is $165 if your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip.
