Answer:

x = 6

Step-by-step explanation:

AC = 5x - 24

AO = 3

AC and BD bisect each other at point O. This means AC ≅ CO.

So, 2(AO) = AC.

2(3) = 5x - 24

Multiply.

6 = 5x - 24

Combine the constants.

30 = 5x

Divide by 5.

x = 6

Multiply and simplify if possible.<br> sqrt 5x(sqrt x-5 sqrt 5)

RSB [31]

Making the assumption that your problem looks like this,
$\sqrt{5x}(\sqrt{x}-5\sqrt{5})$

we use the distributive property to multiply:
$\sqrt{5x}\times \sqrt{x}-\sqrt{5x}\times5\sqrt{5}
\\
\\ \sqrt{5x^2} - 5\sqrt{25x}
\\
\\ x\sqrt{5}-25\sqrt{x}$

Please help me with this question :)

Answer:

y>5/6

Step-by-step explanation:

5y+3>-7y+13

5y+7y>13-3

12y/12>10/12

y>5/6

This is an inequality, which shows where the variable y does or does not exist

from this we can say

y: (-infinity,5/6) (5/6, infinity]

or, y does not exist from (-infinity,5/6)

and does exist from (5/6, infinity]

Which is equivalent?

Arlecino [84]

Steps to simplify:

(2x + 3)(x - 7)

~Use FOIL to multiply

(2x * x) + (2 * -7) + (3 * x) + (3 * -7)

~Simplify

=2x² - 14x + 3x - 21

~Combine Like Terms

2x² + (-14x + 3x) - 21

~Simplify

2x² - 11x - 21 (Option 2)

Best of Luck!
