2(3x)=1(4x-1)
6x=4x-1
Subtract 4x from each side
2x=-1
Divide each side to get x=-1/2
Your answer would be -1/2
Answer:
Step-by-step explanation:
Since, the given question is incomplete but to solve these kind of questions,
Use the formula of the scale factor,
Scale factor = 
From the question ΔE'F'G' is the image formed by the dilation of preimage ΔEFG.
Therefore, 
FG = 
By substituting any value of F'G' given in the question we can evaluate the measure of side FG.
Answer: I dunno
Step-by-step explanation:
25^2+40x+16
= (5x + 4)(5x + 4)
and
25x^2-16
= (5x)^2 -(4)^2
= (5x + 4)(5x - 4)
Both have same factor (5x + 4)
