Answer:
C. Their slopes are equal.
Step-by-step explanation:
Given : If two lines are parallel.
To find : which statement must be true.
Solution : We have given that If two lines are parallel.
We know that two parallel line have same slope
By rise over run :
Therefore, C. Their slopes are equal

Answer:
I think the answer is A.
Step-by-step explanation:
Original shape: 7 x 5 x 225 x 6 x 12 x 45 = 25,515,000
A: 9 x 5 x 225 x 6 x 35 x 12 = 25,515,000
B: 14 x 10 x 255 x 12 x 24 x 45 = 462,672,000
C: 9 x 7 x 225 x 8 x 15 x 45 = 76,545,000
D: 8 x 4 x 225 x 6 x 12 x 35 = 18,144,000
This is probably not the way you would solve it but this is how I did it. Basically I multiplied all the numbers in each shape together.

Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
Answer:
it should be 15
Step-by-step explanation:
Answer: all i can say is this for an edu guess
2 6 and 4 would be 40 or 30
3 5 and 7 would be 110 or 120
8 would be 20 or 10
also this was the first answer
