Drag a value or operation/sign to the boxes to correctly factor the linear expression.

Answers

Answer:

-4( 3x - 0.6y + 12)

Step-by-step explanation:

The expression - 12x + 2.4y - 48 taken a common factor of - 4 we have

- 4(3x - 2y + 12).

What is a factor of a polynomial?

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

The common factor on the other hand is the highest possible value that we can divide each of the given terms.

Given, - 12x + 2.4y - 48.

- 12x + 8y - 48.

Taking - 4 as the common factor we'll have

- 4(3x - 2y + 12).

Step-by-step Explanation:

We are going to solve this problem using integration by parts. We can write the integrand as

[tex]\dfrac{4x}{x^2+4x+3} = \dfrac{4x}{(x+3)(x+1)}[/tex]

[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:= \dfrac{A}{x+3} + \dfrac{B}{x+1}[/tex]

[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:= \dfrac{Ax + A + Bx + 3B}{x^2+4x+3}[/tex]

[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:=\dfrac{(A+B)x + (A+3B)}{x^2+4x+3}[/tex]

Comparing the above term to the left hand side, we can see that

(A + B)x = 4x

A + 3B = 0

Solving for A and B, we find that A = 6 and B = -2 so our integrand becomes

[tex]\dfrac{4x}{x^2+4x+3} = \dfrac{6}{x+3} - \dfrac{2}{x+1}[/tex]

We can now easily integrate this expression as follows:

[tex]\displaystyle \int{\dfrac{4x}{x^2+4x+3}}dx = 6\int{\dfrac{dx}{x+3}} - 2\int{\dfrac{dx}{x+1}}[/tex]

[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:= 6\ln|x+3| - 2\ln|x+1| + C[/tex]

Of the 64 students on a field trip to a museum, five-eighths brought their lunch. How many students brought their own lunch?

A. 39
B. 46
C. 40
D. 38

Answers

Answer:

C. 40

Step-by-step explanation:

1. To find how many students brought their own lunch, we have to multiply 5/8 by 64.  

[tex]\frac{5}{8} * 64[/tex] [tex]\frac{5}{1}* 8[/tex] [tex]40[/tex]

Therefore, the answer is C. 40.

The correct answer is 40 (C)
To find this answer, you must divide the amount of students by the denominator, which would be 64/8 which is 8. Then, you must multiply by the numerator, (8x5) which is 40.

5x + 20 - 5 = 180

5x + 15 = 180
