Answer:
Step-by-step explanation:
Answer:
Prime: x^2 + 17x - 30.
Difference of 2 squares: 256x^4 - 49x^2.
GCF: 4x^2 - 24x + 144.
Perfect Square trinomial: 4a^6 - 28a^3 + 49
Factoring Trinomial: b^2 + 5b - 36.
Step-by-step explanation:
1. x^2 + 17x - 30 will not factor.
2. 256x^4 - 49x^2 = (16x^2 + 7x)(16x^2 - 7x)
3. 4x^2 - 24x + 144 = 4(x^2 - 6x + 36).
4. 4a^6 - 28a^3 + 49 = (2a^3 - 7)^2.
5. b^2 + 5b - 36 = (b + 9)(b - 4).

Answer:
C
Step-by-step explanation:
The line of best fit is a linear function that is closest to all the points and shows the trend in the data. Since the data is going up ultimately, the slope of the line will be positive. Only B and C are options.
To find the best fit, draw a line through the center of the most points. This line will have as its y-intercept a value around 12 and a gentle slope. This means the answer choice is C.
Rachel and her sister Fran together can paint the living room in 
hours
Given that
Rachel can paint half of the living room in 1 hour
Fran can paint 
th part of the living room in 1 hour
Let's assume together they paint the living room in x hours
⇒ together they can paint 
th part of the living room in 1 hour
By proportions,
⇒
+= {using operation proportions and addition}
⇒
=
⇒x=
⇒ together they can paint th part of the living room in 1 hour
It means, Rachel and her sister Fran together can paint the living room in hours
