What is the positive solution to the equation 64x2 + 12x = 1.

Mathematics
1 answer:
Inga [223]3 years ago
3 0

Answer:

1/16

Step-by-step explanation:

Here: 64x^2+12x = 1

Then, 64x^2 +12x -1=0

The delta = 12^2 - 4*64*(-1)= 400 = 20^2

These two solutions are:

(-12+20)/(2*64)=  8/(2*8*8)= 1/16

(-12-20)/(2*64) but this is negatif.

1/16 is the positif solution.

Hope that useful for you.

The length of a rectangle is 10m greater than the width. The area is 24m^2
Ivan

Answer:

length: 12m

width: 2m

Step-by-step explanation:

24 = a*w

a = w+10

then:

24 = (w+10)w

24 = w*w + 10*w

24 = w² + 10w

0 = w² + 10 - 24

w = {-10±√((10²)-(4*1*-24))} / (2*1)

w = {-10±√(100+96)} / 2

w = {-10±√196} / 2

w = {-10±14} / 2

only positive numbers:

w = {-10+14}/2

w = 4/2

w = 2m

a = w+10

a = 2 + 10

a = 12m

Check:

24 = 12*2
