Answer: 5

explanation:

4m-2=6
———
3

multiply 3 on both sides to cancel the 3 out

4m-2=18

add 2 from both sides to cancel the 2 out

4m=20

divide both sides by 4 to cancel out the 4

Answer:

m = 5

Step-by-step explanation:

4m - 2 / 3 = 6

4m - 2 / 3 * 3 = 4m - 2

6 * 3 = 18

4m - 2 = 18

4m - 2 + 2 = 4m

18 + 2 = 20

4m = 20

4m / 4 = m

20 / 4 5

m = 5

Answer:

Step-by-step explanation:

The formula for surface area is SA = 2lw + 2wh + 2lh

W = width

L= length

H = height

A = 2(wl + hl + hw)

2·(6·3+2·3+2·6)

Simplify that down to get the answer 72

A= [2, 3; 2, 1], B=[3; 5]. Find AB & BA if possible

oksano4ka [1.4K]

Answer:

The value of AB is $\left[\begin{array}{ccc}21\\11\end{array}\right]$ and it's not possible to multiply BA.

Step-by-step explanation:

Consider the provided matrices.

$A=\left[\begin{array}{ccc}2&3\\2&1\end{array}\right]$ , $B=\left[\begin{array}{ccc}3\\5\end{array}\right]$

Two matrices can be multiplied if and only if first matrix has an order m × n and second matrix has an order n × v.

Multiply AB

Matrix A has order 2 × 2 and matrix B has order 2 × 1. So according to rule we can multiply both the matrix as shown:

$AB=\left[\begin{array}{ccc}2&3\\2&1\end{array}\right] \left[\begin{array}{ccc}3\\5\end{array}\right]$

$AB=\left[\begin{array}{ccc}2\times 3+3\times 5\\2\times 3+1\times 5\end{array}\right]$

$AB=\left[\begin{array}{ccc}6+15\\6+5\end{array}\right]$

$AB=\left[\begin{array}{ccc}21\\11\end{array}\right]$

Hence, the value of AB is $\left[\begin{array}{ccc}21\\11\end{array}\right]$

Now calculate the value of BA as shown:

Multiply BA

Matrix B has order 2 × 1 and matrix A has order 2 × 2. So according to rule we cannot multiply both the matrix.

We can multiply two matrix if first matrix has an order m × n and second matrix has an order n × v.

That means number of column of first matrix should be equal to the number of rows of second matrix.

Hence, it's not possible to multiply BA.

What is the diameter of the circle?

Hatshy [7]

Hello!

The circumference is the diameter multiplied by pi. To find the diameter we will divide the circumference by pi (3.14).

1,133.54/3.14=361

361 is the diameter of the circle.

I hope this helps!
