A 4
B 14
C 1
D 7

the answer is A

2x-1=x+3

x=4

A. 4

Step-by-step explanation:

First off, x + 3 needs to equal 2x - 1, since the parallel sides of the parallelogram have the same length. Let's check A first, which says x = 4.

I) Substitute equations:

x + 3 = 2x - 1

4 + 3 = 2(4) - 1

II) Solve:

4 + 3 = 2(4) - 1

7 = 2(4) - 1

7 = 8 - 1

7 = 7

x = 4

answer:

c 60% on edg

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
