In between 2 and 3. Closer to 3 than 2. A little bit after 2.5
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!
Answer:
Step-by-step explanation:
See attachment for proper question
From the attachment, triangle DEF is an image of ABC
By comparing the position of the angles, the following sides are similar
AB to DE
AC to DF
BC to EF
By dividing the similar sides, we calculate the scale of dilation.
To calculate DF, we make use of sides AC and DF as comparison:
Substitute 2 for Scale and 2 for AC
Make DF the subject
