Answer:
7x
Step-by-step explanation:
It equals 28 just like the problem with parentheses, 7x .
Answer:
x - 6
Step-by-step explanation:
(4x2 + x - 5) - (5x2 - 1)
According to the order of operations, parenthesis come first so we will solve what is in the parenthesis first.
Then we do the multiplication because it comes before addition and subtraction.
4x2 = 8
Now we have 8 + x - 5
Combine like terms and 8-5=3 so we have 3 + x
Now for the second one.
5x2=10
10-1=9
Subtracting this from the first expression we have:
3+x-9 =
x - 6
The correct answer is A. -22,14
it would be a ratio5:6
Step-by-step explanation:
If a third plane could be drawn which contains both lines a and b, then lines a and b must be parallel. <span>if two lines do not intersect on the same plane, they are parallel. Furthermore, if a line is in a plane and another line is in a parallel plane, you cannot draw another plane </span><span>which contains both lines a and b, only if the lines are parallel.</span>
