Trying to make honor roll <me out

which equation has exactly one solution?
a. 1/2x-2=2x-1/2
b. 1/2x-2=1/2x+2
c. 1/2x-2=1/2x+ -1/2
d. 1/2x-1/2=1/2x+2

  A. 1/2x-2=2x-1/2

Step-by-step explanation:

The other equations are all some form of ...

  0 = <something not zero>

which has no solutions.

Subtract the left side in each case:

  A: 0 = 3/2x +3/2 . . . x = -1

  B: 0 = 4 . . . . . . . . . . . no solution

  C: 0 = 3/2 . . . . . . . . . no solution

  D: 0 = 5/2 . . . . . . . . . no solution

A

Step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
