181 is the only palindrome that has digits that when multiplied together give you 8.

Hope that helps :)

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30

Natasha_Volkova [10]

Answer:

P(2)=0 then x-2 is a factor of P(x)

Step-by-step explanation:

To see if (x-2) is a factor just plug in 2 for x into the polynomial expression.

2(2)^3-3(2)^2-17(2)+30

2(8)-3(4)-34+30

16-12-34+30

4-34+30

-30+30

Since P(2)=0 then x-2 is a factor

Erin is flying a kite. She knows that 260 feet of the kite

lianna [129]

Answer:

100 ft high

Step-by-step explanation:

We know that Erin, the kite, and her friend create a right triangle since the friend is standing directly under the kite and in front of Erin.

Thus, we can use the Pythagorean theorem to find the height of the kite.

We can let the side the distance be at represents Erin and the kite's distance be EK (aka the hypotenuse), the side that represents Erin and her friend's distance be EF and the side that represents the kite and the friend's distance be KF.

The theorem says that a^2 + b^2 = c^2, where a and b are the two shortest sides and c is the hypotenuse.

We already have the measure of the hypotenuse (260 ft) and one of the shorter sides (240), so we have:

$KF^2+240^2=260^2\\KF^2+57600=67600\\KF^2=10000\\\sqrt{(KF^2=10000)} \\KF=100$

Which is a way to write 2x2x2x5x5 with exponent and two bases

artcher [175]

Answer: 2^3 * 5^2.
Exclamation: Since 2 is multiplied out three times, you have 2 to the third power. Same goes for the five- since it’s there twice, that’s 5 to the second power. That brings us to 2^3 * 5^2

What is -4y-3=5-3y+6-19

antiseptic1488 [7]

Answer:

y = 5

Step-by-step explanation:

This is a multi-step equation, so you can solve for the variable 'y' by using a series of steps:

1. Combine like terms:

-4y - 3 = 5 - 3y + 6 -19 or -4y - 3 = -3y - 8

2. Isolate the variable using inverse (opposite operations):

Add 8 to both sides: -4y - 3 + 8 = -3y - 8 + 8 or -4y + 5 = -3y

Add -4y to both sides: -4y + 5 + 4y = -3y + 4y

3. Solve for 'y'

5 = y
