Answer:

The product can be calculated.

The resulting matrix will have 3 rows and 3 columns.

Step-by-step explanation:

Matrix multiplication

To find the product of two matrices is only possible when the number of columns of the first matrix is equal to the number of rows of the second matrix.

If X is the first matrix with dimensions (n x m) and Y is the second matrix with dimensions (m x p), the product XY is possible and the dimensions of the resulting matrix are (n x p).

Matrix A has two rows and three columns (2x3)

Matric C has three rows and two columns (3x2)

If we wanted to calculate the product CA, the number of columns of C must be equal to the number of rows of A.

Since both numbers are 2, the product can be calculated.

The resulting matrix will have 3 rows and 3 columns.

both of them give their Rs.100 so now it's Rs.200 so pay RS 200 and they'll get Rs 50 as the remain

The number of ways of spending Rs. 150 will be 3.

Combination and permutation are two different ways of grouping elements of a set into subsets in mathematics. The elements of the subset can be listed in any order in a combination. The elements of the subset are listed in a specific order in a permutation.

Given that Raman and Raj go to a party each having Rs. 100, If they decide to expend Rs. 150.

The number of the spending will be calculated as,

Raman + Raj = 150

100 + 50 = 150

50 + 100 = 150

75 + 75 = 150

The number of ways will be three.

Step-by-step explanation:

A trinomial is an algebraic expression having three terms in it.

A. 8x  

Not a trinomial because, it contains only one term.

B. 3y +5y2 + y

A trinomial because, it contains three terms.

C. 6x2

Answer:

Step-by-step explanation:

The remaining work is to identify the values of x that make the factors zero:

4x +45 = 0

  x = -45/4 . . . . negative dimensions are not useful

x -10 = 0

  x = 10

The width is x, so the width is 10.

The length is 4x+5, so the length is 4·10+5 = 45.

The rectangle has a width, x, of 10 and a length of 45.

Answer:

The perimeter is equal to 240.

Step-by-step explanation:

Since  the shape is a regular polygon, the sides are equal to each other, so those two equations are equal to each other.

So, to solve for x, then to find perimeter, we need to set the equations equal to each other.

5x + 10 = 7x + 4

Subtract 5x  and -4 from both sides.

6 = 2x

Divide each side by 2.

3 = x

Now, we plug it into one of the equations and multiply by 6 (6 sides in the regular polygon).

5( 6 + 2 )

40

40 * 6 = 240

The perimeter is equal to 240.

Perimeter of the regular polygon is 150 unit

Given:

Equal first side of regular polygon = 7x + 4

Equal second side of regular polygon = 5(x + 2)

Find:

Perimeter of the regular polygon

Computation:

We know that side of regular polygon are equal

7x + 4 = 5(x + 2)

7x + 4 = 5x + 10

7x - 5x = 10 - 4

2x = 6

x = 3

So,

Side of regular polygon = 7x + 4

Side of regular polygon = 7(3) + 4

Side of regular polygon = 25 unit

We know that given polygon is hexagon

Perimeter of hexagon = 6(a)

Perimeter of hexagon = 6(25)

Perimeter of hexagon = 150 unit
