Answer:
11.5cm
Step-by-step explanation:
1.2 meters = 120 centimeters
(for the 9 of them, with each being 9.5cm) = 9 * 9.5
=85.5cm
(For The rest of the remaining 3 books): 120cm - 85.5cm
=34.5cm
Each of them would be 34.5 / 3
=11.5cm
Answer:
It is rigid
It is isometric
The size is preserved
Step-by-step explanation:
Given that Triangle ABC was translated to form A'B'C', then both triangles are congruent triangles.
A translation only moves the figure, preserving the size.
Because the size is preserved, it is a rigid transformation or isometric transformation.
Answer:
k = 3
Step-by-step explanation:
Expanding the first term, we find 1/x at 10(kx)²(1/x)³ = 10k²/x
Expanding the first term, we find 1/x at 8*1⁷(-2/x)¹ = -16/x
Then
10k² - 16 = 74
k = 3
