Answer:
Problem #1: Option D, Line 4
Problem #2
PART A: Option 1, 2xy(2x−y)(2x+y)(4x2+y2)
PART B: Option 3, greatest common factor, Option 6, repeated difference of squares
Step-by-step explanation:
Problem #1
Step 1: Factor P(x) = 8x^3 + 20x^2 − 18x − 45
4x^2(2x + 5) - 9(2x + 5)
(4x^2 - 9)(2x + 5)
<em>(2x + 3)(2x - 3)(2x + 5)</em>
<em />
Answer: Option D, Line 4
Problem #2
<u>Part A: Factor</u>
2xy(16x^4 - y^4)
2xy(4x^2 + y^2)(2x + y)(2x - y)
Answer: Option 1, 2xy(2x−y)(2x+y)(4x2+y2)
Part B: Find the methods
Option 3, greatest common factor
Option 6, repeated difference of squares
Answer:
B
Step-by-step explanation:
2(1/4)=2.25, 2.23, -2, -2(1/5)=-2.20
2.25 is larger than 2.23
2.23 is larger than -2
And -2 is larger than -2.20
Hope this helps!
Answer: 40.45 or 40 9/20
Step-by-step explanation:
2 miles * 7 days = 14
3/5 miles * 7 days = 4.2
5 miles * 4 days = 20
3/4 miles * 4 days = 2.25
then you add those together, and thus 40.45
