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
Hello :
an equation is : y-5 = 0( x+7)...(the slope =0 '<span> horizontal line ' )</span> y=5

Answer:
Step-by-step explanation:
What I would do is convert everything to have a denominator of 10 so it could be easier to add.
6 would equal 60/10
7 would equal 70/10
2/5 would equal 4/10
now add all together
60/10 + 70/10 + 4/10 +9/10 and you get 143/10. If you wanted to simplify you would get 14 3/10 or 14.30
