Answer:

13.31 x $10^{46}$

Step-by-step explanation:

So, if we take the two equations, and add the normal numbers together, we have: 5.97 + 7.34 = 13.31

Then if we add the two tens together it would be: $10^2^2$ + $10^{24$ = 10 to the power of 46.

The equation would be 13.31 x $10^{46}$

I'm not an expert, so sorry if this is wrong.

Solve the system of equations using multiplication. 3x – 3y = –3 5x – y = –13 What is the solution of the system?

love history [14]

ANSWER

The solution is

x=-3,y=-2

EXPLANATION

First equation

3x – 3y = –3

Second Equation:

5x – y = –13

Multiply the second equation by 3 to get:

Third equation:

15x-3y=-39

Subtract the first equation from the third equation:

$15x - 3x = - 39 - - 3$

$12x = - 36$

Divide both sides by 12,

$x = \frac{ - 36}{12} = - 3$

Put x=-3 into the first equation:

$3( - 3) - 3y = - 3$

$- 9 - 3y = - 3$

Group like terms,

$- 3y = - 3 + 9$

$- 3y = 6$

$y = - 2$

The solution is

x=-3,y=-2

Multiply factor 8(x-3y)(x+3y) to determine the original polynomial

Inessa [10]

If I'm doing this correctly, you would need to multiply everything inside the parenthesis by 8. So it would be 8x-24y·8x+24y. I'm sorry if that's not right, but that is my interpretation of the problem. Hope I was of some assistance :)
