Step-by-step explanation:
18x²-8
= 2(9x²-4)
= 2(3x+2)(3x-2)
3 - 13x - 7x^2 - (5x^2 + 12x - 10)
Distributing the negative over the parentheses chamges the signs:-
= 3 - 13x - 7x^2 - 5x^2 - 12x + 10
adding like terms:-
= -12x^2 - 25x + 13 (answer).
Its B
The answer is B. 50+3x=104. andrea drove 18 miles, because 104-50= 54 and 54 divided by 3=18
5x-6 because 6 less than means after and a number times 5 would be 5x so it would be 5x-6
