8 0

Answer:

Its the first choice.

Step-by-step explanation:

x^2+4x-4 = 8

x^2 + 4x - 4 - 8 = 0

x^2 + 4x - 12 = 0

(x + 6)(x - 2) = 0

x = -6, 2.

What is the value of x?
OLga [1]

Answer:

x = 24

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

<em>a</em> = a leg

<em>b</em> = another leg

<em>c</em> = hypotenuse

Step 1: Plug in known variables

x² + 10² = 26²

Step 2: Evaluate

x² + 100 = 676

Step 3: Isolate <em>x </em>term

x² = 576

Step 4: Isolate <em>x</em>

√x² = √576

x = 24

Well Basically, it’s kinda a struggle to understand this math your explaining:( <br> Well, 3/6 = 8/?
lord [1]
16 will go where the question mark is located

So 3/6 = 8/16

Think of it like this: if you had three slices of pizza out of 6 total, then you had half the pizza. The same goes for if you had 8 slices out of 16 total

You can use the cross multiplication rule to find x
3/6 = 8/x
3*x = 6*8
3x = 48
3x/3 = 48/3
x = 16

What is the greatest possible integer value of x for which startroot x minus 5 endroot is an imaginary number? 3 4 5 6
Sauron [17]

The greatest possible integer value of x for which \sqrt{x - 5} is an imaginary number is 4

<h3>How to determine the greatest possible integer?</h3>

The root expression is given as:

\sqrt{x - 5}

For the above number to be a complex number, the greatest value of the radicand must be -1.

So, we have:

x - 5 = -1

Add 5 to both sides

x = 4

Hence, the greatest possible integer value of x for which \sqrt{x - 5} is an imaginary number is 4
