X^2-3x = x(x-3)
x^2-9 = x^2 - 3^2 = (x-3)(x+3)
HCF = x-3

X²－3x＝x(x－3)
x²－9＝x²－3²＝(x－3)(x＋3)
∴the highest common factor of x²－3x and x²－9 is x－3

Hope my answer helped u :)

Find the area and perimeter

pashok25 [27]

Answer:

Part 1) The perimeter is $P=172\pi\ ft$

Part 2) The area is $A=1,204\pi\ ft^2$

Step-by-step explanation:

Part 1) Find the perimeter

we know that

The perimeter is equal to the circumference of the exterior circle plus the circumference of the interior circle

$P=2\pi (50)+2\pi (36)$

$P=2\pi (86)\\P=172\pi\ ft$

Part 2) Find the area

we know that

The area of the figure is equal to the area of the larger circle minus the area of the smaller circle

$A=\pi (50)^2-\pi (36)^2$

$A=\pi (1,204)$

$A=1,204\pi\ ft^2$

The number of zeroes at the end of the cube root of the number1000

ivolga24 [154]

Hey there!

The answer to your question is one zero.

To solve this, we can first start by finding the cube root.

$\sqrt[3]{1000}$

The answer to this is $10$ , because $10 * 10 * 10 = 1000$

Now, we can see that there is one zero at the end of $10$ .

Hope it helps and have a great day/night! Stay safe!
