Find the solutions of the given equation. <br><br> 25x^2+64=289

AleksAgata [21]

Answer:

Step-by-step explanation:

Start by subtracting 64 from both sides:

$25x^2=225$

Factor this by taking roots. Divide both sides by 25 first:

$x^2=9$

We "undo" a square by taking the square roots of both sides. Taking the square root leaves the possibilities of both the positive and negative roots of 9. Therefore, the solutions to this are

$x=\sqrt{3},-\sqrt{3}$

How many solutions are there to 3x-10(x+2) =13-7x

Vaselesa [24]

This is the following way to solve this problem:

3x-10(x+2)=13-7x

3x-10x-20=13-7x (multiply 10 times what's in the parentheses)

-7x-20=13-7x ( subtract 3x from -10x)

-7x-20-13=-7x ( since the 13 is positive, when we move it to the other

side, we change it's sign, so now we subtract 13 from 20

-7x-7=-7x

-7=-7x+7x ( we do the same thing we did above, now with the -7x)

-7=x

x=-7

Answer: x = -7
