Correct answer is C
5x×25x−1125x+1 = 5x×52x−253x+3
= 5x+2x−253x+3
= 53x−253x+3
= 53x−2−3x−3
= 5−5

Correct answer is C
Area of a square = 4(5) where S is each sides of the square
Perimeter = 20(given)
4S = 20
S = 204
= 5
Area s2 = 52

Multiply (3x + 5y + 4z) by (2x - 3y + z)
6x2 + xy - 15y2 + 4z2 + 11xz - 7yz
6x2 + 3xy - 15y2 + 4z2
6x2 + 3xy - y2 + 4z2
6x2 + 3xy - 15y + z2
Correct answer is A
(3x + 5y + 4z)(2x - 3y + z)
6x2 + 9xy + 3x2 + 10xy - 15y2 + 5yz + 8xz - 12yz + 4z2
= 6x2 + xy - 15y2 + 4z2 + 11xz - 7yz
