<h3>Hey Mate Here Is Your Answer:-</h3>

3) \:  \:  \: 4(2y + z) - 3(3y + z) \\  \\  = 8y + 4z - 9y + 3z \\  \\  =  - y + 7z

4) \:  \:  \:  \: x(4x - 2) - 3x(x + 1) \\  \\  = 4x {}^{2}  - 2x - 3 {x}^{2}   - 3x \\  \\  =  {x}^{2}  - 5x

5) a> \:  \: 3(2 + c) \\  \\  = 6 + 3c

b> \:  \:  \: 2a(b - 4) \\  \\  = 2ab - 8a

c> \:  \:  \: ab(b + c) \\  \\  = ab {}^{2}  + abc

Matrix a is a 6 × 5 matrix. which order of matrix can be multiplied by matrix a to create matrix ab?
mezya [45]

Order (B) 5 × 6 of the matrix can be multiplied by matrix a to create matrix ab.

<h3>What is a matrix?</h3>
  • A matrix is a rectangular array or table of numbers, symbols, or expressions that are organized in rows and columns to represent a mathematical object or an attribute of such an object in mathematics.
  • For instance, consider a matrix with two rows and three columns.

To find the order of matrix:

  • We must first check the dimension of two matrices, say matrix A by matrix B, before we may multiply them.
  • Multiplication is achievable if the number of columns in the first matrix, A, equals the number of rows in the second matrix.
  • Dimension is assigned to the provided matrix: 6 × 5
  • This means the given matrix contains six rows and five columns.
  • As a result, the second matrix MUST have 5 rows in order for multiplication to be POSSIBLE.
  • The only matrix with 5 rows among the above alternatives is the matrix with dimension (B) 5 × 6.

To prove:

  • In other words, the inner products of the dimensions should be equal.
  • That is; (a × b)(b × a) is possible but (a ×b)(c × b) is impossible.
  • The dimensions of the matrix are given by, row × column.

Therefore, order (B) 5 × 6 of the matrix can be multiplied by matrix a to create matrix ab.

Andrews [41]

Answer:

a = 1 and b = 14 or a = 14 and b = 1

Step-by-step explanation:

This means that ab = 14 and a + b = 15. Simple guess and check reveals (1, 14) or (14, 1).

What is the solution to the equation 7^3x ≈ 9 ?
egoroff_w [7]
7^{3x}\approx9\\\\\log_77^{3x}\approx\log_79\\\\3x\approx\log_79\ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{x\approx\dfrac{\log_79}{3}=\frac{1}{3}\log_79=\log_79^\frac{1}{3}=\log_7\sqrt[3]9}
