Answer:
The answer to all of those questions would be x=-1.8
Step-by-step explanation:
7x(x + 1.8) = 0 - Distribute through the Parenthesis -
7x^2 + 12.6x = 0
x(7x + 12.6) = 0
x = 0
7x + 12.6 = 0
7x = -12.6
x = -12.6/7
x = -1.8
so x = 0 or x = -1.8
Answer:
62.73 will be the correct answer
To add them, you first need a common denominator.
So multiply <span> 1/4 by 5/5 and 1/5 by 4/4 first.
Now they'll be 5/20 and 4/20.
Add them to get 9/20. </span>
I think that x may equal to -3. Because the sum of a triangle is always 180. 55+54=109 and 180-109=71 and -3+74=71
The answer is 1.
