563/.4 is equal to 1,407.5
Answer:
Part A)
This quadratic expression can be factored by using the difference of squares pattern.
Part B) (5x+y) and (5x-y)
Step-by-step explanation:
Given:
25x^2-y^2
above polynomial can be factorize by using difference of squares formula
a2-b2=(a+b)(a-b)
25x^2-y^2= (5x-y)(5x+y)
so for part A)
correct option is This quadratic expression can be factored by using the difference of squares pattern.
Part B)
As factored above in part A,
the factors of given polynomial 25x^2-y^2 are (5x+y)(5x-y)
so for part B) correct options are (5x+y) and (5x-y) !
36:39 in simplest form is 12:13
Answer:
7,854 cm
Step-by-step explanation:
The area of a circle is given by πr², and the radius is the diameter/2:
100/2=50
π•50²=7,853.98≈7,854
Step-by-step explanation:
3 - 11x
x is "a number".
so, the request is to multiply it by 11 and subtract the result from 3.
