Paraphin [41]

Answer:

I don't know if this is correct but wouldn't it be 560?

Step-by-step explanation:

If you have 10 on one side, you divide 10 by 1/4 to get 40. So you need 40 blocks to fill one side, and 3 1/2 on the other only needs 14. 14*40=560.

Find two matrices A and B such that 2A-3B= [5 0

amm1812

The easy answer: If, say, B is the zero matrix, i.e.

$B=\begin{bmatrix}0&0\\0&0\end{bmatrix}$

then

$2A=\begin{bmatrix}5&0\\-1&2\end{bmatrix}\implies A=\begin{bmatrix}\dfrac52&0\\\\-\dfrac12&1\end{bmatrix}$

Please help ASAP !!!

Answer: x=3

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- Multiply both sides of the equation by 3:

$3(2x-3)=3(\frac{x^2}{3})\\6x-9=x^{2}$

- Now you must make the equation equal to zero as following:

$6x-9=x^{2}\\x^{2}-6x+9=0$

- Factor it, as you can see below. Therefore, you obtain the following result:

$(x-3)(x-3)=0\\(x-3)^2=0\\x=3$
