Answer:
Second option: 81y^4 - 16x^2, the difference of squares
Step-by-step explanation:
(9y^2-4x)(9y^2+4x) is a special product named difference of squares, then we can apply this formula:
(a-b)(a+b)=a^2-b^2, with a=9y^2 and b=4x, then:
(9y^2-4x)(9y^2+4x)=(9y^2)^2 - (4x)^2
(9y^2-4x)(9y^2+4x)=(9)^2 (y^2)^2 - (4)^2 (x)^2
(9y^2-4x)(9y^2+4x)=81y^(2*2) - 16x^2
(9y^2-4x)(9y^2+4x)=81y^4 - 16x^2
Answer:
4
or 4.75
Step-by-step explanation:
first we're going to convert the number into improper fractions.
7
= 
and 2= 
For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply x2, it'll equal the same number.
So now we have 
-, 30-11= 19.
simplified is, 4.
As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.
I hope this helps you!
Answer:
c. $1,291.30
Step-by-step explanation:
Calculation what will his new annual homeowners insurance premium be
