Given the following matrices, find 3A - 2B. (Hint: find 3A and 2B first and then subtract.)

1 answer:

7 0

Its A
When you multiply a constant k to a matrix, you multiply all the corresponding numbers in the matrix by k.
So 3A would be = 3 9 15 6 and 2b would be = 8 18 0 6 Now subtract it. to get your answer

A and B are two points on square ABCD with coordinates A(1,3) and B(5,3). What are the lengths of the diagonals AC and BD? Round

lilavasa [31]

Answer:

$AC = BD = 5.7$

Step-by-step explanation:

Given

$A = (1,3)$

$B = (5,3)$

Required

The length of the diagonals

First, calculate the length of AB using:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

So, we have:

$AB = \sqrt{(1 - 5)^2 + (3 - 3)^2}$

$AB = \sqrt{(-4)^2 + 0^2}$

$AB = \sqrt{16}$

$AB = 4$

The diagonal of a square is calculated using:

$Diagonal = x\sqrt{2$

Where x is the length of each side.

So:

$AC = BD = AB\sqrt{2}$

$AC = BD = 4\sqrt{2}$

$AC = BD = 5.7$ -- approximated

PLEASE HELP ASAP <3 Express as a trinomial (3x+5) (x+1) :)

Gennadij [26K]

Answer:

$3x^2+8x+5$

Step-by-step explanation:

$(3x+5)(x+1)$

$3x(x+1)+5(x+1)$ Distribute

$3x(x+1)+5(x+1)$ Distribute $3x(x+1)$

$3x^2+3x+5(x+1)$

$3x^{2} +3x+5(x+1)$ Distrbute $5(x+1)$

$3x^2+3x+5x+5$ Combine like terms

$3x^{2} +8x+5$

Answer:

x = 6

Step-by-step explanation:

Okay, so we have a 90 degree angle.

That means:

5x + x + 54 = 90

Simplify and Solve:

6x = 36

x = 6

Hope this helps! :)
