Put the value in equation 

hence only one solution exists
.
Answer:
24 (units)
Step-by-step explanation:
Because Quadrilateral EFGH is being dilated by a scale factor of 3/4, this means that each side of E'F'G'H' gets multiplied by 3/4. In this case, we are going to divide by 3/4 to return to the original figure (or multiply by 4/3 since that is the reciprocal)
This means that side HE is 18/(3/4) = 18(4/3) = 72/3 = 24 units
Answer:297334.8
Step-by-step explanation:
(410.4) (724.5)
=297334.8
General form of any equation is of the form AX+BY+C=0
Here A,B,C are three real numbers
THe given equation is
2x +4y+2=3y+5
To make right side equal to 0 we subtract 3y and 5 both sides
2x+4y+2-3y-5=0
Simplifying like terms
2x+y-3=0
Option B is the right answer
