Answer:

B(12)

Step-by-step explanation:

Constant of proportionality is basically the slope.

Slope = Δy/Δx

here y= distance travelled and x= number of hours

so slope = 36-3/3-0.25= 33/2.75 = 12

Write as a product of 2 binomials and a monomial (factor out as much as possible from each binomial). (14x+21y)(6ab–3a)

mihalych1998 [28]

Answer: The answer is $21a(2x+3y)(2b-1).$

Step-by-step explanation: Given expression is as follows

$E=(14x+21y)(6ab-3a).$

We are to write the above expression "E" as a product of two binomials and a monomial.

A monomial is an expression with a single term and a binomial is an expression with two terms.

So, let us start as follows -

$E\\\\=(14x+21y)(6ab-3a)\\\\=7(2x+3y)3a(2b-1)\\\\=21a(2x+3y)(2b-1).$

Here,

$21a~\textup{is a monomial and}~(2x+3y),~(2b-1)~\textup{are binomials}.$

Thus, the required factorisation is

$E=21a(2x+3y)(2b-1).$

Let U = {q, r, s, t, u, v, w, x, y, z}

Sliva [168]

The Set A’∪ B = { r, t, v, x, z, q, s, y, z }

We have the following sets -

U = {q, r, s, t, u, v, w, x, y, z}

A = {q, s, u, w, y}

B = {q, s, y, z}

C = {v, w, x, y, z}

We have to determine the set represented by - A' ∪ B.

A set is a collection of elements or numbers or objects, represented within the curly brackets { }. For example: {1,2,3,4} is a set of numbers.

According to question, we have -

U = {q, r, s, t, u, v, w, x, y, z} (Universal Set)

A = {q, s, u, w, y}

B = {q, s, y, z}

C = {v, w, x, y, z}

Consider Set A = {q, s, u, w, y}

A' = U - A = {q, r, s, t, u, v, w, x, y, z} - {q, s, u, w, y} = { r, t, v, x, z }

and Set B = {q, s, y, z}

Now -

A' ∪ B = { r, t, v, x, z } ∪ {q, s, y, z} = { r, t, v, x, z, q, s, y, z }

Hence, the Set A’∪ B = { r, t, v, x, z, q, s, y, z }
