63:18
divide both sides by 3
= 21:6
divide by 3 again
= 7:2
Answer:
- y =
+ 7
Step-by-step explanation:
The graph that will lie above the x-axis will be having only positive values throughout its domain,
So, We have to check which graph is having y > 0 for every x.
- y = -
+ 7
clearly y will be negative for many values of x , as coefficient of variable is negative.
- y =
- 7
Put x = 0, you will get y as negative .
- y =
+ 7
Since, Square of anything will always be positive , and here constant term is also positive , so, It will always be positive .
Thus, it is having its graph always above x axis.
Put x = 0 , y = -7, which is negative
Your question doesn't sound complete...the algebraic expression should equal something but this is what I ended up with 9(x+3)
Answer:
Given the expression: 3x10 − 48x2
Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)
<em>answer</em><em>:</em>
<em>3</em><em>x</em><em>²</em><em>(</em><em>x^8-16</em><em>)</em>
Part B: Factor the entire expression completely. Show the steps of your work.
3x²(x^8-16)
3x²((x^)²-4²)
3x²(x⁴+4)(x⁴-4)
3x²(x⁴+4)((x²)²-2²)
3x²(x⁴+4)(x²+2)(x²-2)
