Step-by-step explanation:
so its 2x then squared by 2 then y and squared by 3 all together making 2x^2y^3
Answer:
4(x - 1) = 4x - 4
3x + 6 = 3(x + 2)
Step-by-step explanation:
The first equation is

We simplify to get;

This is not true, therefore this equation has no solution.
The second equation is

Combine like terms:



This has a unique solution.
The 3rd equation is

Group similar terms:

The 4th equation is :


This is always true. The equation has infinite solution.
The 5th equation is:

This also has infinite solution
The 6th equation is

It has a unique solution.
Solution:
Fabric possessed by Da. Shari = 4 Sweaters + 2 Coats + 5 Jackets= 11 in all
Arrangement that Da Shari wants to arrange 4 Sweaters + 2 Coats + 5 Jackets is to put "a sweater first and a jacket last".
After putting a sweater first and jacket last , total fabric which needs to be arranged is (3 Sweaters + 2 Coats + 4 Jackets)=9 in all.
Total number of possible arrangement = (1 sweater) × [9 fabric=(3 Sweaters + 2 Coats + 4 Jackets) arrangement] × (1 Jackets)
= 1! × 9 ! × 1!
= 9 !
= 9 × 8 × 7× 6× 5× 4× 3×2×1
= 362,880 ways
