Answer:
yes the corresponding sides are proportional
Answer:
The factored expression is 2(x² + 5)(x + 3).
Step-by-step explanation:
Hey there!
We can use a factoring technique referred to as "grouping" to solve this problem.
Grouping is used for polynomials with four terms as a quick and easy factoring method to remove the GCF and get down to the initial terms that create the expression/function.
Grouping works in the following matter:
- Given equation: ax³ + bx² + cx + d
- Group a & b, c & d: (ax³ + bx²) + (cx + d)
- Pull GCFs and factors
Let's apply these steps to the given equation.
- Given equation: 2x³ + 6x² + 10x + 30
- Group a & b, c & d: (2x³ + 6x²) + (10x + 30)
- Pull GCFs and factors: 2x²(x + 3) + 10(x + 3)
As you'll see, we have a common term with both sides of the expression. This term, (x + 3), is a valuable asset to the factoring process. This is one of the factors for our expression.
Now, we use our GCFs to create another factor.
- List GCFs: 2x², 10
- Create a term: (2x² + 10)
Finally, we'll need to simplify this one by taking another GCF, 2.
- Pull GCF: 2(x² + 5)
Now that we have this term, we need to understand that this <em>could</em> also be factored further using imaginary numbers, but it is also acceptable to leave it in this form.
Therefore, we have our final factors: 2(x² + 5) and (x + 3).
However, when we factor, we place all of our terms together. This leaves us with the final answer: 2(x² + 5)(x + 3).
Answer:
first question: c. x = 1
6. B. y = -2x - 8
Step-by-step explanation:
first question:
perpendicular means that when it intersects, it makes a right angle.
the equation y = 5 would be parallel to any of the answers with y = ___ because all of those would result in horizontal lines
either of the x = ___ would be perpendicular to y = 5
since it has to pass through the point (1,3) that means that the equation must be x = 1
the equation x = 1 passes through any point beginning with (1 , _)
6.
parallel means that the equations have the same slope. therefore, we can eliminate both A and C
using the given point (-2 , -4),we can plug into the y = mx + b format to solve
m = -2 x = -2 y = -4
-4 = (-2)(-2) + b --> -4 = 4 + b --> b = -8
finally, our equation comes out to be y = -2x - 8
