Please Help!
Jesus Christ, please leave her alone
oof wish i could help but i dont know math... and i came here for the ANSWER oof
Jeez louis, ya'll just dump on Ms. Sue & then no one gets an answer to their question.
People can have opinions but PLEASE keep them to yourself, for the better of everyone, what if I came up & called y'all 'stupid'.
Please be respectful & kind to others, what have we all been taught since like preschool? Treat others how you want to be treated.
Thank you.
The answers are 5^2x5^4 < 5^8
And 2^4x2^4>2^7
No its d nevermind
Answers??
dude shut up, a straight answer is an answer that you don't change your mind on every 5 seconds, idiot.
* means multiply
plz give a straight answer
B
A
is @answer right... lol im not taking a risk
Anonymous is right
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.
simplify the expression
-x(7x - 8)
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.
5k^2 (-6k^2 - 2k + 6)
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.
(2k + 3) (k - 1)
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.
(-2y + 5) (y + 3)
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.
