Step-by-step explanation:

$\\ 20. \: \: ( \frac{ - 3}{4} )(4\frac{1}{6} )$

$\\ = \frac{ - 3}{4} \times \frac{25}{6}$

$\\ = \frac{ - 25}{8}$

$\\ = - 3.125$

$\\ 21. \: \: ( - 3\frac{7}{8} )( - 5\frac{3}{4} )$

$\\ = \frac{ - 31}{8} \times \frac{ - 23}{4}$

$\\ = \frac{713}{32}$

$\\ = 22.28125$

Factor completely 3ab − 5ax + 9b − 15x.

Alik [6]

Answer: The answers are given below.

Step-by-step explanation: We are given to factorise some quadratic expressions.

We will be using the following factorisation formula:

$x^2+ax+bx+ab=(x+a)(x+b).$

The factorisation is as follows:

We have

$(1)~3ab-5ax+9b-15x\\\\=a(3b-5x)+3(3b-5x)\\\\=(3b-5x)(a+3).$

Thus, option (B) $(3b-5x)(a+3)$ is correct.

$(2)~5x(x+3)+6(x+3)\\\\=(x+3)(5x+6).$

Thus, option (B) $(x+3)(5x+6)$ is correct.

$(3)~2cb+7cx+2b+7x\\\\=c(2b+7x)+1(2b+7x)\\\\=(2b+7x)(c+1).$

Thus, option (B) $(2b+7x)(c+1)$ is correct

$(4)~21x^3+35x^2+9x+15\\\\=7x^2(3x+5)+3(3x+5)\\\\=(3x+5)(7x^2+3).$

Thus, option (D) $(3x+5)(7x^2+3)$ is correct.

$(5)~9xy+36x-10y-40\\\\=9x(y+4)-10(y+4)=(y+4)(9x-10).$

Thus, option (C) $(y+4)(9x-10)$ is the correct option.

$(6)~14bx^2-7x^3-4b+2x\\\\=7x^2(2b-x)-2(2b-x)\\\\=(2b-x)(7x^2-2).$

Thus, option (B) $(2b-x)(7x^2-2)$ is the correct option.

$(7)~4xy+9x+24y+54\\\\=x(4y+9)+6(4y+9)\\\\=(4y+9)(x+6).$

Thus, option (D) $(4y+9)(x+6)$ is correct.

Add the polynomials

7nadin3 [17]

Answer:

5x^4 + 3x^2 + 4x

Step-by-step explanation:

Basically what your doing is 5x^4 + 4x - 6 + 3x^2 + 6

There aren't any common things we can add apart from the - 6 and 6

So do

-6 + 6 = 0

You end with the answer
