Answer:
x=25 or x=0
Step-by-step explanation:
4x(x−25)=0
Step 1: Simplify both sides of the equation.
4x2−100x=0
For this equation: a=4, b=-100, c=0
4x2+−100x+0=0
Step 2: Use quadratic formula with a=4, b=-100, c=0.
x=−b±√b2−4ac over 2a
x=−(−100)±√(−100)2−4(4)(0) over 2(4)
x=100±√10000 over 8
x=25 or x=0
4 and 7 and 8 and 9 and10
Answer:
T=4 plz make brainlest answer
Step-by-step explanation:
Monday overall cost 36+5t
Tuesday overall cost 20+9t
36+5t=20+9t
-20 -20
16+5t =9t
-5t -5t
16=4t
t=4
Check
36+5t=20+9t (t=4)
36+20=20+36
It works
- 90, 50 , 40
And
60, 50, 70
