Answer: 40n-20
Step-by-step explanation:
14n-4+6n+12n-4+8n-12
14n+6n+12n+8n-4-4-12
40n-20
The number is 84. If you find numbers that equal 12 that are both one digit numbers, you have 9 and 3, 8 and 4, and 7 and 5. If you put 48, together they equal 12. If you divide 84 by 7, you will get 12. 84 reversed is 48, which is 4 times 12. So if you times 84 by 4/7, you will get 48.

Frame is 24x32 since the frame is 2.5in wide you have to add 2.5in twice to both width and length
a.29in x 37in
b.2ft 4in x 3ft 1in
c.0yd 2ft 4in x 1yd 1in
The term in that equation is 3x 7x and -9 hope this helps
