Hey there, x^2 -6x+25=0 Per quadratic formula, roots of ax^2+bx+c are x=[-b+sqrt(b^2-4ac)]/2a and x=[-b-sqrt(b^2-4ac)]/2a
In this example, a=1, b=-6, and c=25 So, x= [6+sqrt(36-100)]/2 and x= [6-sqrt(36-100)]/2 => x = [6+sqrt(-64)]/2 and x = [6-sqrt(-64)]/2 => x = 3+4i and x= 3-4i
Hope this helped you alot!!!!!!!!
Soup cost $10 for 3 cans. Josh spent $40 on soup. How many cans did he buy?
Answers
he bought 12 cans:) because if 3 cans are 10$ and he spent 40$ just multiply 4 (the 40 dollars)times 3 (the amount of cans you get per 10 dollars).Hope this helped!

Math question please answer thankss

4-3x=8x+7
PLEASE HELP I GIVE THANKS!
Answers
Since 8x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 8x from both sides. 4−3x−8x=7
Add −3x and −8x to get −11x. 4−11x=7
Move 4 to the right hand side of the equation by subtracting 4 from both sides. −11x=−4+7
Add −4 and 7 to get 3. −11x=3
Divide each term in the equation by −11.
x=−3/11
Subtract four from either side: -3x = 8x +3 Subtract 8x from either side -11x = 3 Divide both side by negative eleven x = -11/3 That's your answer! Hope this helps!
