Answer:
Step-by-step explanation:
1) Split the second term in 
into two terms.
1 - Multiply the coefficient of the first term by the constant term.
2 - Ask: Which two numbers add up to 2 and multiply to -35?
7 and -5.
3 - Split 2x as the sum of 7x and -5x.
2) Factor out common terms in the first two terms, then in the last two terms.
3) Factor out the common term x+1.
4) Solve for x.
1 - Ask: When will (x+1)(7x-5) equal zero?
When x + 1 0 or 7x-5=0
2 - Solve each of the 2 equations above.
Each pencil costs $0.40 because
4.00/10=.40
You would take 280-105=175 miles away and take 105 and divide that by your time 1.5 too get 70 mph
Answer: 127º
Step-by-step explanation: The sum of internal angles from a polygons is equal to 180 (n-2) where n is the number of sides for the polygon
so the polygon from the picture has 6 sides then the total sum of internal angles is:720º
On the other hand, added all the internal angles we have: 112º+133º+128º+100º+120º=593º
the angle denoted by x is equal to 720º-593º= 127º
