First consider (x+c)^2 where c is just a random constant. if we expand this by foil (which is distributive property twice), we get x^2 + 2cx+ c^2. we want to find c^2 and to do that, we can first find c. we can find c by looking at the 2cx term. this term should match with 12x, so therefore 2c = 12 so c = 6. this also implies that c^2 = 36.
note that for this problem i was working backwards which is a very powerful problem solving tool: start with what you want to attain, and then see how you can go from where you are now to get to your destination.
let me know if you have any questions!!!
Answer:x=750
Step-by-step explanation:
2/3(x)+ 1/4(x) + 375
(9/12)x - (3/12)x = 375
(6/12)x + 375
Answer:
c
Step-by-step explanation:
formula l=PRT
bring PT to right side we get
l/PT = R
or
R=l/PT
Answer:
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output.
Answer:
X=5
Step-by-step explanation:
, then divide both sides by 18 which gives you 5.666667 but you cant buy half a ball they can only afford 5 balls with $12 left over.
