Answer:
6x² - xy - 15y²
Step-by-step explanation:
To multiply these two binomials together, we can use FOIL. FOIL stands for:
First: Multiply the first terms of the binomials together.
Outer: Multiply the first term of the first binomial by the second term of the second binomial.
Inner: Multiply the second term of the first binomial by the first term of the second binomial.
Last: Multiply the second (last) terms of the two binomials together.
(3x - 5y)(2x + 3y) = (3x)(2x) + (3x)(3y) + (-5y)(2x) + (-5y)(3y)
= 6x² + 9xy - 10xy - 15y²
= 6x² - xy - 15y²
I hope you find my answer helpful.
There are 15 ways to choose 2 of the kittens from the litter
The given parameters are:
The number of ways to select the 2 kittens is:
Ways =
This gives
Ways =
The combination formula is:
So, we have:
Evaluate the difference
Expand
Evaluate the quotient
So, we have:
Ways = 15
Hence, there are 15 ways to choose 2 of the kittens from the litter

1) π
2)5/4
3) √7
4) √3/2
Answer:
2) 5/4
Step-by-step explanation:
The other numbers arent irrationals because they have infinite decimals, and that cant be expresed in a fraction (sorry if i said something wrong im learning english)
The scientific notation of the number 0.00057 is,
⇒ 5.7 × 10⁻⁴
We have to give that,
A number is,
⇒ 0.00057
Since Scientific notation is a way of writing very large or very small numbers.
For example; 230,000,000 can be written in scientific notation as
2.3 x 10⁸
Hence, Write the number in scientific notation as,
⇒ 0.00057
⇒ 5.7 × 10⁻⁴
