Answer:
2.
A. GCF: 5x
B. GCF: 1
3.
A. 12x² + 38x - 14
B. 9x² - 6x + 1
C. 3x² + 4x - 5
Step-by-step explanation:
2.
a.
5x² - 30x
5x (x - 6)
GCF: 5x
b.
-12x² - 3xy - 4y²
GCF: 1
3.
a.
(2x + 7)(6x - 2)
2x(6x - 2) + 7(6x - 2)
12x² - 4x + 42x - 14
12x² + 38x - 14
b.
(3x - 1)²
(3x - 1)(3x - 1)
3x(3x - 1) - 1(3x - 1)
9x² - 3x - 3x + 1
9x² - 6x + 1
c.
(x + 3)(3x - 2) - (3x - 1)
3x(x + 3) - 2(x + 3)
3x² + 9x - 2x - 6
3x² + 7x - 6 - (3x - 1)
3x² + 7x - 6 - 3x + 1
3x² + 4x - 5
I hope this helps!
The probability that an animal has stripes will be 0.86.
<h3>How to calculate the probability?</h3>
The probability that an animal has stripes will be:
= Orange stripes + Brown stripes + Grey stripes
= 0.16 + 0.3 + 0.4
= 0.86
The probability that an animal doesn't have stripes will be:
= 1 - 0.86
= 0.14
Therefore, the probability that an animal doesn't have stripes is 0.14.

Answer: Choice A
The number line graph is visually showing every number that is 19 or smaller; hence
Note the use of a closed or filled in circle at the endpoint (in contrast to an open circle). This indicates we are including the endpoint 19 as part of the solution set, and that's why we go for "or equal to" as part of the inequality sign.
