Answer:
3???
Step-by-step explanation:
Answer:
The factored form would be (8g + 7h)(2g - 5h)
Step-by-step explanation:
In order to find this, we need to use factors of 16g^2 in the front of the parenthesis. We also need to use factors of -35h^2 in the second side. Now we try these in the parenthesis and FOIL until we get an appropriate middle term.
Answer:
r= 
Step-by-step explanation:
The sum to infinity of a geometric series is calculated as
S∞ = 
; | r | < 1
where a₁ is the first term and r the common ratio
here a₁ = 15 and S∞ = 45 , then
45 = 
( multiply both sides by (1 - r ) )
45(1 - r) = 15 ( divide both sides by 45 )
1 - r = 
= 
( subtract 1 from both sides )
- r = - 1 = - ( multiply both sides by - 1 )
r =
