R = C / (2 * pi)
r = 125.6 / (2 * 3.14)
r = 125.6 / 6.28
r = 20 <== the radius
diameter of a circle is twice the radius......2 * 20 = 40 <== diameter

"Enlargement" here implies that the two pentagons are similar. Because of similarity, the following equation of ratios must be true: 7/15 = x/7. Then 15x=49, and x = 49/15 = 3.27 cm, approximately.
Rounded to the nearest tenth, that comes to 3.3 cm.
For this question you can say:
16g - 48g = -32g
and 32h - 40h = -8h
so you will have:
-32g - 8h and you can factor -8 so you will have:
-8(4g + h) :)))
i hope this is helpful
have a nice day
Answer:
Option C - (-28p⁵-21p⁴+7p³)
Step-by-step explanation:
=> -7p³×4p²= -28p⁵---- 1
=> -7p³×3p= -21p⁴------ 2
=> -7p× (-1)= 7p³---- 3p
Add 1+2+3
=> (-28p⁵-21p⁴+7p³)
Hope this helps you.
