Please Help!

Answer 1

what does * stands for

Answer 2

* means multiply

Answer 3

this is why I dislike you Ms. Sue, you will answer a comment on a question, but you don't answer the question, how stupid could you be?

Please be respectful & kind to others, what have we all been taught since like preschool? Treat others how you want to be treated.

1 is a

Answer 12

No its d nevermind

Answer 13

plz give a straight answer

Answer 14

MANAZEDRT it is kinda rude to assume everyone is straight like I am not so therefore I can not give a straight answer. Guess we got a homophobe yikes

is @answer right... lol im not taking a risk

Answer 18

The answers are 5^2x5^4 < 5^8
And 2^4x2^4>2^7

Answer 19

Anonymous is right

Answer 20

Yes, Anonymous is correct. The first expression is false (answer is d) and the second expression is true (answer is a). The correct reasoning is:

a. 4^3 * 4^5 = 4^8, which is less than 4^12. Therefore, the expression is false.
b. 5^2 * 5^3 = 5^5, which is less than 5^6. Therefore, the expression is false.
c. 3^2 * 3^4 = 3^(2+4) = 3^6, which is equal to 3^6. Therefore, the expression is true.
d. 5^2 * 5^4 = 5^(2+4) = 5^6, which is equal to 5^6. Therefore, the expression is true.

a. 2^4 * 2^4 = 2^(4+4) = 2^8, which is greater than 2^7. Therefore, the expression is true.
b. 3^2 * 3^6 = 3^(2+6) = 3^8, which is greater than 3^7. Therefore, the expression is false.
c. 4^3 * 4^5 = 4^(3+5) = 4^8, which is less than 4^8. Therefore, the expression is false.
d. 5^2 * 5^3 = 5^(2+3) = 5^5, which is equal to 5^5. Therefore, the expression is true.

Answer 21

simplify the expression

-x(7x - 8)

Answer 22

The given expression is:

-x(7x - 8)

Multiplying -x by each term inside the bracket, we get:

= -x*7x + x*8

= -7x^2 + 8x

Therefore, the simplified expression is -7x^2 + 8x.

Answer 23

5k^2 (-6k^2 - 2k + 6)

Answer 24

To simplify the given expression, we use distributive property of multiplication:

5k^2(-6k^2 - 2k + 6) = -30k^4 - 10k^3 + 30k^2

Therefore, the simplified expression is -30k^4 - 10k^3 + 30k^2.

Answer 25

(2k + 3) (k - 1)

Answer 26

To multiply the given expressions, we can use the distributive property or the FOIL (First, Outer, Inner, Last) method. The FOIL method involves multiplying the First terms, the Outer terms, the Inner terms, and the Last terms, and then adding them together. Here's how it works:

(2k + 3) (k - 1) = (2k)(k) + (2k)(-1) + (3)(k) + (3)(-1)

= 2k^2 - 2k + 3k - 3

= 2k^2 + k - 3

Therefore, (2k + 3) (k - 1) simplifies to 2k^2 + k - 3.

Answer 27

(-2y + 5) (y + 3)

Answer 28

To multiply the given expressions, we can use the distributive property or the FOIL (First, Outer, Inner, Last) method. Here's how to use the FOIL method:

(-2y + 5) (y + 3) = (-2y)(y) + (-2y)(3) + (5)(y) + (5)(3)

= -2y^2 - 6y + 5y + 15

= -2y^2 - y + 15

Therefore, the simplified form of the expression (-2y + 5) (y + 3) is -2y^2 - y + 15.
