Answer:

The required expression is 4x^2-25

Step-by-step explanation:

The difference of squares formula is given by

(a+b)(a-b)=a^2-b^2

We have been given that one factor is 2x+5. Hence, a = 2x, b = 5

It means that other factor must be (a-b) = (2x-5)

Hence, in order to find the expression, we can multiply the factors.

(2x+5)(2x-5)

Using the difference of squares formula

(2x+5)(2x-5)\\\\=(2x)^2-5^2\\\\4x^2-25

Therefore, the required expression is 4x^2-25

Answer:

  A. 3×3

  B. [0, 1, 5]

  C. (rows, columns) = (# equations, # variables) for matrix A; vector x remains unchanged; vector b has a row for each equation.

Step-by-step explanation:

A. The matrix A has a row for each equation and a column for each variable. The entries in each column of a given row are the coefficients of the corresponding variable in the equation the row represents. If the variable is missing, its coefficient is zero.

This system of equations has 3 equations in 3 variables, so matrix A has dimensions ...

  A dimensions = (rows, columns) = (# equations, # variables) = (3, 3)

Matrix A is 3×3.

__

B. The second row of A represents the second equation:

  0x_1+1x_2+5x_3=-1

The coefficients of the variables are 0, 1, 5. These are the entries in row 2 of matrix A.

__

C. As stated in part A, the size of matrix A will match the number of equations and variables in the system. If the number of variables remains the same, the number of rows of A (and b) will reflect the number of equations. (The number of columns of A (and rows of x) will reflect the number of variables.)

CAN SOMEONE HELP ME WITH THIS MATH QUESTION ITS ABOUT TRANSLATION
earnstyle [38]

Answer:

(- 4, 1 )

Step-by-step explanation:

A translation (x + 1), y - 3 ) means add 1 to the original x- coordinate and subtract 3 from the original y- coordinate.

B = (- 5, 4 ), thus

B' = (- 5 + 1, 4 - 3 ) = (- 4, 1 )

Jacob spent 3 hours skiing and snowboarding. He skied for 1 hours 25 minutes. How long did he spend snowboarding?
lord [1]

Answer:

Hours spent for snowboarding = 1 hour 35 minutes

Step-by-step explanation:

Total hours spent for skiing and snowboarding = 3 hours

Hours spent for skiing = 1 hours 25 minutes

How long did he spend snowboarding?

Hours spent for snowboarding = Total hours spent for skiing and snowboarding - Hours spent for skiing = 1 hours 25 minutes

= 3 hours - 1 hours 25 minutes

1 hour = 60 minutes

3 hours = 180 minutes

1 hours 25 minutes = 85 minutes

3 hours - 1 hours 25 minutes

= 180 minutes - 85 minutes

= 95 minutes

95 minutes = 1 hour 35 minutes

Hours spent for snowboarding = 1 hour 35 minutes
