Lets width od field is x , x>0 (if x<0 it is no sense) yards and length is (x+40)yards
So square of field is x(x+40)=6000
x²+40x=6000
x²+40x-6000=0
(x+100)(x-60)=0
x₁=-100 no sense
x₂=60 yards - width of field
x+40=x+60=100 yards - length of field
Answer: 60 yards - width of field, 100 yards - length of field
Answer:
Step-by-step explanation:
y = -2x + 5 ⇒ 2x + y = 5
6x + 3y = 15 ⇒ 2x + y = 5
The two equations are equivalent, so there are infinitely many solutions.
Looking at the info that is given it gives you the answer. If you were trying to find how much more he needs you need to know,
1: How much the music player is.
2: How much you already have.
3:How much you get each week.
So the answer would be C.
Answer:
75
Step-by-step explanation:
The measure of two supplementary angles = 15:21
The angles are 15x , 21x
15x + 21x = 180 {Supplementary}
36x = 180
x = 180/36
x = 5
Smallest angle = 15 * 5 = 75
