Answer: True
The opposite sides of a parallelogram are congruent or equal in length. The opposite sides are also parallel. It might help to think of a rectangle, which is a special case of a parallelogram.
Let n be the number. The difference of the number and six is n-6. Then three times the difference of the number and six is 3·(n-6). This number 3·(n-6) increased by four times the number n, then
3·(n-6)=4·n.
Solve it:
3·n-3·6=4n,
3n-4n=18,
-n=18,
n=-18.
Answer: n=-18 and expression is 3·(n-6)=4·n.
Answer:
Distribute the 3 to the parenthesis, and the -1 to the parenthesis.
This will result to:
3x-9-x+4
2x-5
Answer:
The same way you tell if a parabola opens up or down, by the leading coefficient of the variable.
Step-by-step explanation:
Since the x-axis is positive to the right, a positive leading coefficient (3) means it opens to the right. eg. And a negative leading coefficient (-2) means it opens to the left.
