Answer: x=7
Step-by-step explanation:
(5x-40)+7 = 2
5x-33 = 2
5x = 35
x = 35/5
x = 7
Answer:
length= 100 width=70
Step-by-step explanation:
The perimeter of a rectangular field is 340 yds.
The length is 30 yds longer than the width.
2(l + w) = 340
l + w = 170
w + 30 + w = 170
2w = 140
w = 70
Hence the dimensions:
Length: 100 yds.
Width: 70 yds.
Answer:
I believe it's C I had this on my test and I got it right
If d=6, there are two real solutions.
Rule if d=discriminant:
d>0, two real solutions
d=0, one real solution
d<0, no real solutions (but there are two imaginary solutions)
