I NEED THIS NOW! Please give the answer with a solution! (Solving Quadratic Equations by Extracting Square Roots)

1. 3x^2=13

2. 5x^2-18=0

thank you thank you

Asystem of equation is shown below 6x - 2y equals 3 . and 5x + 3y equals 4. would you solve by substitution or elimination? and why

Which is the correct first step in finding the area of the base of a cylinder with a volume of 26x cubic meters and a height of 6.5 meters? v=bh 6.5=b(26x) v=bh v=26pi+(6.5) v=bh v=26pi(6.5) v=bh 26pi=b(6.5)

Fast! find the length of cu. the triangles are similar. show your work.
