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]

5 Answers: Choice A, B, C, D, E
Basically, it's everything except choice F.
=========================================================
Explanation:
The number 26 is a whole number since the set of whole numbers is {0,1,2,3,4,...} and it's also an integer as well because the set of integers includes the negative counterparts. That takes care of answer choices A and C.
The number 26 is rational because 26 = 26/1 which is a ratio or fraction of integers. Because it's rational, that means it cannot be irrational. The term "irrational" means "not rational". This means answer choice B is true while choice F is not true.
The number 26 is a natural number. The set of natural numbers is {1,2,3,4,...} which is effectively almost identical to the set of whole numbers, except 0 isn't involved. This is why choice D is another answer.
Lastly, choice E is an answer because 26 is a real number. Assuming you haven't learned about complex numbers yet, every number you encounter is a real number.
---------
So to summarize, the number 26 is...
a whole numbera rational numberan integera natural numbera real numberThe only thing that it's not is irrational (which would contradict it being rational).

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.

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
= 6
