Answer:
the two lengths= 194 each side
teh two widths= 49 on each side
194+194+49+49= 486
Step-by-step explanation:
486= 2l+2w
l=4w-2
486-2w=2l -divide that by 2
243-w=l
243-w=4w-2
245=5w -divide that by 5
49=w
l=4(49)-2
l=194
w=49

Answer:
(4x + 2)( 2x - 10)
Step-by-step explanation:
Answer: the rules are
+(+) Two like signs become a positive sign
−(−) 6−(−3) = 6 + 3 = 9
+(−) Two unlike signs become a negative sign
−(+)
Step-by-step explanation:
Example: 3+(+2) = 3 + 2 = 5, 6−(−3) = 6 + 3 = 9, 7+(−2) = 7 − 2 = 5,8−(+2) = 8 − 2 = 6 hope this helps you :)
Answer:
= - 5n - 2
Step-by-step explanation:
There is a common difference between consecutive terms, that is
- 12 - (- 7) = - 17 - (- 12) = - 5
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 5, then
= - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
