In the expression 2(x+4)-12=44, x=24 true or false

2 answers:

This is true. If you solve the equation you get x = 24. First, use the distributive property and multiply 2 by x and 4. Now your equation is 2x + 8 - 12 = 44. Next, you add like terms so -12 + 8 is -4. So 2x - 4 = 44 Now you can add 4 to the right and you get 48. So 2x = 48. Lastly, divide by 2 and your answer is x = 24. True.

I need help please?!!!!

The multiplicative inverse of a number x is a number y such that their product xy is 1.

So, we want a number such that

$10\cdot x = 1$

Divide both sides by 10:

$x=\dfrac{1}{10}$

$(f \circ g)(x) = \sqrt{36x^2+96x+65}\\\\\\(f \circ g)(2) = \sqrt{401}\\\\$

========================================================

Work shown for part 1

$f(x) = \sqrt{x^2-2x+2}\\\\f(g(x)) = \sqrt{(g(x))^2-2(g(x))+2}\\\\f(g(x)) = \sqrt{(-6x-7)^2-2(-6x-7)+2}\\\\f(g(x)) = \sqrt{36x^2+84x+49+12x+14+2}\\\\f(g(x)) = \sqrt{36x^2+96x+65}\\\\(f \circ g)(x) = \sqrt{36x^2+96x+65}\\\\$

----------------------------------

Work shown for part 2

$(f \circ g)(x) = \sqrt{36x^2+96x+65}\\\\(f \circ g)(2) = \sqrt{36(2)^2+96(2)+65}\\\\(f \circ g)(2) = \sqrt{401}\\\\$
