25*25=625. The answer is 25.
Answer:
S^2 = r^2 + t^2
Step-by-step explanation:
Also you can write it as:
S=sqrt( r^2 +t^2)
according to the choices you have
Hello there!
8m² - 4(7m³ + 5n²)
You wanna start by using the distributive property
=8n² - (-4)(7m³) + (-4)(5n²)
= 8n² - 28m³ - 20n²
= -28m³ - 12m²
So a going a whole circle around is 180 so if it goes 1/4 of it, it will be 720
The sum formula for a geometric sequaence is:
sum(n) = a1(1-r^n)/1-r
Where n is the number of terms, a1 is the first term and r is the common ratio:
s(8) = 3(1-1/2^8) / (1-1/2)
s(8) = 3(1-1/256) / 1/2
s(8) = 2 253/256 / 1/2
s(8) = 765/128
The answer is C.
