Since area is length times width, it would be the factors of the equation for the area.
X2+11x+28 factors into...
Length is x+7 so...
Width is x+4
Angle a is one ninth as large as its complement angle b
a+b=180
a=9b
a=18
b=162
iş right answer plese let me know
The function is y=2x
this means that the solutions will have the form (x, y)=(x,2x).
For example: (0,0),(1,2),(2,4),(3,6) are solutions.
The first answer choice satisfies the above conditions.
The second answer choice contains (2,2), and (2,6), both of which do not satisfy the (x,2x) condition, so it's not correct.
The third answer choice contains (4,2), which again does not satisfy (x,2x), so not the right answer.
Answer:
1 - 3 (1 quarter is 25 and a dime is 10, so, 3.)
4 - 10
6 - 15
14 - 33
Step-by-step explanation:
The answer is B since he bought 4 in all it is x+y =4 . x=dvd y= blue ray discs .
so 2x + 5y =11
2x since dvds are $2
5y since blue ray discs are $5
11 since that’s the total
