$a=8\\b=?\\\\Area=64\\\\Area=a\cdot b\\\\8\cdot b=64\ \ \ \ /:8\\\\b=64:8\\\\b=8\\\\Perimeter=2a+2b\\\\Perimeter=2\cdot8+2\cdot8=16+16=32$

Write a recursive formula for each explicit formula

Crazy boy [7]

Answer:

38. $a_1=107,\ a_n=a_{n-1}-1$

40. $a_1=87,\ a_n=a_{n-1}+52$

Step-by-step explanation:

38. <u>Given explicit formula:</u>

$a_n=108-n$

When $n=1,$ then $a_1=108-1=107$

When $n=2,$ then $a_2=108-2=106$

When $n=3,$ then $a_3=108-3=105$

When $n=4,$ then $a_4=108-4=104$

and so on

You can see that each next number is 1 less than previous number, so the recursive formula is

$a_n=a_{n-1}-1$

40. <u>Given explicit formula:</u>

$a_n=35+52n$

When $n=1,$ then $a_1=35+52\cdot 1=87$

When $n=2,$ then $a_2=35+52\cdot 2=139$

When $n=3,$ then $a_3=35+52\cdot 3=191$

When $n=4,$ then $a_4=35+52\cdot 4=243$

and so on

You can see that each next number is 52 more than previous number, so the recursive formula is

$a_n=a_{n-1}+52$

Grandpa's age is 7 years less than 6 times Junior's

7nadin3 [17]

Answer:

Junior is 11 and Grandpa is 59

Step-by-step explanation:

G = 6J - 7 Get G by itself

G + J = 70

- J -J

G = -J + 70 Set the two equations equal to each other

6J - 7 = -J + 70

+J +J Add J to both sides

7J - 7 = 70

+ 7 +7 Add 7 to both sides

7J = 77 Divide both sdies by 7

J = 11
