1. (3 + xz)(–3 + xz)
2. (y² – xy)(y² + xy)
3. (64y2 + x2)(–x2 + 64y2)
Explanation
The difference of 2 squares is in the form (a+b)(a-c).
(3 + xz)(–3 + xz) = (3 + xz)(xz -3)
= (xz + 3)(xz - 3)
= x²y²-3xy+3xy-9
=x²y² - 3²
(y² – xy)(y² + xy) = y⁴+xy³-xy³-x²y²
= y⁴ - x²y²
(64y2 + x2)(–x2 + 64y2)= (64y²+x²)(64y²-x²)
= 4096y⁴-64y²x²+64y²x²-x⁴
= 4096y⁴ - x⁴
Ayy you doing e2020:) Ok the answer would be B. 1/3
600 miles / 27 miles per gallon = 22.22 gallons
22.22 * 1.99 = $44.22 total cost
Answer: C. y = 10x + 15
Step-by-step explanation:
He has already watched 15 movies so that's plus 15
And now he wants to watch 10 movies per week, we don't know how many weeks so that's '<em>x</em>' in this equation.
If he watches movies for <em>x </em>weeks that's 10 times <em>x </em>which is the 10x in the equation.
Hope that helped!
