Ax^2+bx+c=0
expanded, that is the x term
in
(ax+c)(dx+e), the coefient of the b term is cd+ae
so
(2x-1)(1x+5)
the b term is (-1)(1)+(2)(5)=-1+10=9
b is 9
The value of x in the triangle is 50
The angles in a triangle add up to 180.
So, we have:
x + x + 2x - 20 = 180
Add 20 to both sides
x + x + 2x = 200
Evaluate the like terms
4x =200
Divide both sides by 4
x =50
Hence, the value of x in the triangle is 50

Answer:
Emma can complete the calls alone in 6 days, which means she can complete 
of the calls in one day. So, Emma’s rate per day is . Jackson can complete the calls alone in 
days, which means he can complete 
of the calls in one day. So, Jackson’s rate per day is . Because they’re working together, the time, 
, is the same for both.
Multiply across the table to find the part of the task each has completed. Use the equation work completed = (rate)(time) to fill in the last column cells.

Answer: 720
Step-by-step explanation:
480 : 16 marked
480-16 = 464
They saw 464 unmarked squirrels and 16 marked squirrels
464/16 = 29
They saw 29 unmarked squirrels for every 1 makes squirrel
29 * 24 = 696
They would have seen 696 unmarked squirrels for the 24 marked squirrels.
696 + 24 = 720
