(9+w)w=252 or w(w+9)=252.
The quadratic equation applies: w²+9w-252=0=(w+21)(w-12), so w=12, because a negative zero is meaningless.
So the dimensions are width=12 in and length=21 in.
Total of what? You can put the question in the comment section of this comment.
Answer: Sabre read the most
Step-by-step explanation:
35% of 40 is 14, which is more than 12
1- I didn't understand it
2).. (a/b)² (a/b)⁸
= (a/b)²+⁸ = (a/b)¹⁰
3) 3-⁵ = 1/3⁵ = 1/243
4) (x/y)"
d/dx (x/y) = (1/y)
d/dx (1/y) = 0
5) (2m⁴n³)⁵
= 2⁵ × (m⁴)⁵ × (n³)⁵
= 32 × m²⁰ × n¹⁵
= 32m²⁰n¹⁵
