Values of the elements in the Matrix are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.

A collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix, are the integers. In addition to many other areas of mathematics, matrices have numerous applications in the fields of engineering, physics, economics, and statistics.

given, the sum of each row is equal to the sum of each column equals the sum of all diagonals.

Since, the sum of column C₁ = 3 + -2 + 1 = 2

the sum of Row R₁ = 3 + A₂₁ + 1 = 4 + A₂₁

Since this is equal to the sum of column C₁

thus, 4 + A₂₁ = 2

A₂₁ = -2

the sum of column C₂ = A₂₁ + A₂₂ + 4

C₂ = -2 + A₂₂ + 4

C₂ = A₂₂ + 2

Since this is equal to the sum of column C₁

2 = A₂₂ + 2

A₂₂ = 0

the sum of Row R₂ = -2 + A₂₂ + A₂₃

R₂ = -2 + 0 + A₂₃

Since this is equal to the sum of column C₁

2 = -2 + A₂₃

A₂₃ = 4

the sum of Row R₃ = -1 + 4 + A₃₃

R₃ = -3 + A₃₃

Since this is equal to the sum of column C₁

2 = -3 + A₃₃

A₃₃ = 5

therefore, the values of the matrix's elements are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.

Answer:

990, C

Step-by-step explanation:

The formula for the surface area of the bottom cushion is

A = 2wl + 2lh + 2hw (w is width, l is length, h is height)

w = 18, l = 21, h = 3

A = 2(18)(21) + 2(21)(3) + 2(3)(18)

A = 2(378) + 2(63) + 2(54)

A = 756 + 126 + 108

A = 990 (C)

Answer:

D. x < 3

Step-by-step explanation:

3x + 7 < 16

To solve, we have to isolate x.

3x + 7 < 16

Subtract 7 from both sides :

3x < 9

Divide 3 from both sides :

x < 3

Now in some cases, you could say that the inequality sign would switch, but this is only when you divide by a negative sign, so keep that in mind.

Step-by-step explanation:

if each can hold 1/8 of a bag, then 8 can hold 1 bag. if there are 15 bags, and each bag can fill 8 planters, then 15 bags can fill 15x8 planters, or 120

pls mark brainliest <3

Total 120 planters can be filled with 15 bags of topsoil.

Important information:

First, we need to find the unit rate planters per bag and then we need to find the planters for 15 bags.

According to the given information,

1 planter holds [tex]\dfrac{1}{8}[/tex] of a bag.
