Let n represent the unknown numbers.
*we add 2 and 4 to the numbers so that we are sure that they will be even*
n + (n+2) + (n+4) = - 300 *simplify*
n + n + 2 + n + 4 = - 300
3n+6=-300
-6 -6
--------------- *Get constants and variables to either side*
3n = - 306
--- ------ *Isolate the variables*
3 3
n= - 102
Then plug this in for the above values
n+2= - 102+2= -100
n+4= - 102+4 = -98
Answer:
In mathematics, a parabola is a plane curve that is mirror-symmetrical and is approximately U-shaped.
The rule for the linear graph is y=mx
Answer:
x=-16
Step-by-step explanation:
We are given with the equation
We are asked to solve it for x.
Distributing over bracket and simplifying
Adding 8 on both sides
Dividing both sides by -3
