Answer:
g - 16 is the answer
Step-by-step explanation:
−2 (3g−8g+8) − 9g
Distribute:
= (−2) (3g) + (−2) (−8g) + (−2) (8) + −9g
= −6g + 16g + −16 + − 9g
Combine Like Terms:
=−6g + 16g+ −16+ −9g
= (−6g+16g+−9g) + (−16)
=g+−16
Answer:
=g−16
For number one, the answer will be C because the ratio between the side and the perimeter of the Pentagon will be 1/5 or 2/10 or 3/15. For number 2, we know that the Pentagon had 5 sides, and the side of it is 8, so the perimeter of this Pentagon will be 8+8+8+8+8 or 40 inches, which is C. Hope it help!

Answer:
x + 14 = 2(x + 6)
x = 2
Step-by-step explanation:
Let
Algebra book age = x
Chemistry book age = x + 8
In 6 years time
Chemistry book age = x + 8 + 6
= x + 14
Algebra book age = x + 6
the chemistry book will be twice as old as the Algebra book.
x + 14 = 2(x+6)
x + 14 = 2x + 12
x - 2x = 12 - 14
- x = - 2
Divide both sides by -1
x = 2
Check:
Chemistry book age = x + 14
= 2 + 14
= 16
Algebra book age = x + 6
= 2 + 6
= 8
Good!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
