Answer:

Step-by-step explanation:

The trouble maker is √(x - 3).

If you try and put in (say) - 1 for x, what happens is that you are taking the square root of -1 - 3 = - 4. At this level of math, you can't take the square root of a number < 3. So that modified is what you put in the blank.

The domain for f(x) is all the real numbers larger than or equal to 3.

The rectangle below has an area of 14x^4 + 6x^2 square meters. The width of the rectangle (in meters) is equal to the greatest c

julia-pushkina [17]

Answer:

$w=2x^2$ and $l = (7x^2+3)$

Step-by-step explanation:

The area of a rectangle is $14x^4+6x^2$ which factors through GCF, by finding the greatest common monomial factor between the two.

$14x^4+6x^2 = 2*7x^4 + 2*3x^2 = 2x^2(7x^2+3)$

The length and width of the rectangle are $w=2x^2$ and $l = (7x^2+3)$ .

Answer:

See Below.

Step-by-step explanation:

In the given figure, AP = BP = PC.

And we want to prove that ∠ABC is a right angle.

Since AP = BP and BP = PC, we can create two isosceles triangles: ΔAPB and ΔCPB.

By the definition of isosceles triangles, in ΔAPB, ∠PAB and ∠PBA are equivalent. Let the measure of each of them be x°.

Likewise, in ΔCPB, ∠PCB and ∠PBC are equivalent.

And since AP = BP = PC, each of the angles∠PCB and ∠PBC will also be equivalent to x°.

And since the sum of the interior angles of a triangle total 180°, we acquire:

$\angle PAB+\angle PBA+\angle PCB+\angle PBC=180$

Since they are all equivalent:

$4x=180$

Hence:

$x=45^\circ$

∠ABC is the sum of ∠PBA and ∠PBC, each of which measures 45°. Hence:

$\angle ABC=\angle PBA+\angle PBC=45+45=90^\circ$
