Answer:
1 6/7
Step-by-step explanation:
26.) 3(2)² - 8(-3)²
= 3*4 - 8 + 9
= 12 - 8 + 9 = 13
27.) I 7 - 4(2) I
7 - 8 = -1, but since this is absolute value, which is a number's distance from zero, your answer for 27 would be a positive one.
28.) (-2)² + 2(-3 * 1)
= 4 + 2(-3)
= 4 + (-6) = 4 - 6 = -2
29.) 7(-4)² + 5 / 4(1) - (-5)
=7 * 16 + 5 / 4 + 5
= 112 + 5 / 9 = 117/9 = 13
30.) Product: the result of a multiplication problem
Increased by: multiplied by
3(n * 7)
31.) 2n - 1

Answer:
A. Enlargement, 1.5
Step-by-step explanation:
Comparing the two triangles, it would be observed that ΔD'E'F' is larger than ΔDEF. This implies that ΔDEF has been multiplied by a scale factor.
To determine the scale factor used, consider the side DE and D'E' of the two triangles:
scale factor = 
= 
scale factor = 1.5
Therefore, ΔDEF was enlarged to ΔD'E'F' using a scale factor of 1.5. Then the correct option is A.
The blank space in the task content should be filled with; a 270° rotation about point P.
<h3>What transformation is first to effect the image formation?</h3>
It follows from the transformation described in the task content that; Triangle KLM from which triangle K'L'M' is rotated 270 degrees about point P and then translated down and to the right.
It therefore follows from observation. that the first transformation is; a 270° rotation about point P.
