<span>Because lines extend infinitely in both directions, every pair of lines either intersect once, or don't intersect at all. The pairs of lines that never intersect are called parallel lines. Although parallel lines are usually thought of in pairs, an infinite number of lines can be parallel to one another.</span>
For this case we must indicate the value of the following expression, expressed in scientific notation:
We have that for multiplication properties of powers of the same base, the same base is placed and the exponents are added:
Then, rewriting the expression we have:
Answer:
They are congruent.
So, 4x - 26 = 3x + 4
x=30
C. i think that is the correct answer
Heh, this is a tricky one. This would get you messed up, thinking it'd be 15 hours. But if they worked together, they would go faster, making it simple subtraction, which means 9-6 = 3.
3 hours. Have a great day.
