Answer:

w = $\sqrt{147}$

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

w² + 7² = 14²

w² + 49 = 196 ( subtract 49 from both sides )

w² = 147 ( take the square root of both sides )

w = $\sqrt{147}$

Hey there!

<h2>ANSWER: $f=-16$ </h2><h2>EXPLANATION:</h2>

$\frac{f}{4}-5=-9$

Simplify both sides and you get:

$\frac{1}{4}f-5=9$

Now add 5 to both sides and you get:

$\frac{1}{4}f=-4$

Now you have to multiply both sides and you get:

$f=-16(ANSWER)$

Hope this helps!

Answer:

$\large\boxed{x\leq-27}$

Step-by-step explanation:

$\dfrac{x}{-9}\geq3\qquad\text{change the signs}\\\\\dfrac{x}{9}\leq-3\qquad\text{multiply both sides by 9}\\\\9\!\!\!\!\diagup^1\cdot\dfrac{x}{9\!\!\!\!\diagup_1}\leq(-3)(9)\\\\x\leq-27$

Which of the following best describes the equation below?

Reika [66]

4(x + 9) + 5x = 9x - 36

=> 4x + 36 + 5x = 9x - 36

=> 9x + 36 = 9x - 36

=> 9x - 9x = -36 - 36

=> 0 = -72

You can see that the equation doesn't hold true.

So there is no solution for this equation.

Answer is C. no real solutions
