Step-by-step explanation:
Answer:
x=6, x= -5
Step-by-step explanation:
Factor the equation
x^2 - x - 30 = 0 ----> (x-6)(x+5)=0
Next find the solution by setting those in the paranthesis equal to zero.
x-6=0 ----> x= 6
x+5=0 ----> x= -5
Answer:
t = 480
Step-by-step explanation:
When we have equations with variables, we always want to isolate the variable, so lets get rid of 4 first.
Add 4 to both sides :
-96 = -t/5
Multiply both sides by the denominator :
-480 = -t
Divide both sides by negative 1 :
t = 480
