Answer:

X=-5

Step-by-step explanation:

√4x+8=x+3

Simplifies to:

2x+8=x+3

Let's solve your equation step-by-step.

2x+8=x+3

Step 1: Subtract x from both sides.

2x+8−x=x+3−x

x+8=3

Step 2: Subtract 8 from both sides.

x+8−8=3−8

x=−5

Find the zeros of y= x - 4x - 9 by completing the square.

Paraphin [41]

The zeros for the given equation are A. $x = {2 \pm \sqrt{13}}.$

Step-by-step explanation:

Step 1:

To solve for x in a polynomial equation, we use the formula

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}.$

Here a is the coefficient of $x^{2}$ , b is the coefficient of $x$ and c is the coefficient of the constant term.

In the given equation, $a = 1, b = -4, c = -9$ .

Step 2:

Substituting the values of a, b, and c in the equation, we get

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a} =\frac{-(-4) \pm \sqrt{(-4)^{2}-4 (1)(-9)}}{2 (1)} = \frac{4 \pm \sqrt{(16+36}}{2 }.$

$\frac{4 \pm \sqrt{(16+36}}{2 } = \frac{4 \pm \sqrt{(52}}{2 } = \frac{4 \pm2 \sqrt{(13}}{2 }= {2 \pm \sqrt{13}}.$

So the answer is option A. $x = {2 \pm \sqrt{13}}.$

A cone and cylinder have the same height and their bases are congruent circles. If the volume of the cylinder is 120 cubic inche

NikAS [45]

Answer:

Volume of cone = 40 in³

Step-by-step explanation:

Given:

Volume of cylinder = 120 in³

Height of cylinder = Height of cone

Radius of cylinder = Radius of cone

Find:

Volume of cone

Computation:

Volume of cylinder = πr²h = 120 in³

Volume of cone = (1/3)πr²h

So,

Volume of cone = (1/3)(120)

Volume of cone = 40 in³
