Answer:
x= 2.28
or, x= 0.219
Step-by-step explanation:
2x²-5x+1 =0
a= 2, b= -5 and c= 1
x= (-b <u>+</u> √(b²-4ac))/2a
= (5 <u>+</u> √(25-8))/4
= (5 <u>+</u> √17)/4
Answer: 0
Step-by-step explanation: In order to identify the <em>y-intercept</em> of this equation, we want to get this equation into slope-intercept form which is more commonly known as y = mx + b form.
The problem is our equation doesn't match up quite so well with the formula y = mx + b. Our slope or <em>m</em> which is represented by the coefficient of the <em>x</em> <em>term</em> is clearly +4 but what is our y-intercept or b?
Well y = 4x can be thought of as y = 4x + 0 so you can see that our b or y-intercept equals 0.
Answer:
Step-by-step explanation:
L=2W
P=2(L+W), using L=2W this becomes
P=2(2W+W)
P=2(3W)
P=6W, given P=150
6W=150
W=25, and since L=2W
L=50 so
L=50ft and W=25ft
Answer:
12
Step-by-step explanation:
Side 9 applies to side 18
Side 7 applies to side 14
the factor is multiply by two
So 6 times 2 is 12
