Answer:

Option 1st is correct

[(3a^2+(-3a^2)]+(-5ab+8ab)+ (b^2+2b^2)

Step-by-step explanation:

Given the expression:

(3a^2-5ab+b^2)+(-3a^2+2b^2+8ab)

Like terms are those which have same variable to the same powers.

Open the bracket:

3a^2 -5ab+b^2+(-3a^2)+2b^2+8ab

⇒[(3a^2+(-3a^2)]+(-5ab+8ab)+ (b^2+2b^2)

Therefore, the sum of the polynomials rewritten with like terms grouped together is:

[(3a^2+(-3a^2)]+(-5ab+8ab)+ (b^2+2b^2)

A public swimming pool that holds 45,000 gallons of water is going to be drained for maintenance at a rate of 100 gallons per mi
crimeas [40]

Answer:

450 minutes

Step-by-step explanation:

Given

w = 45000 - 100t

Required

Determine how long it'll take to empty the pool

Being empty means there's no water in the pool.

So, we have to set w to 0 to get the value of t

i.e w = 0

Substitute 0 for w in w = 45000 - 100t

0 = 45000 - 100t

Collect Like Terms

100t = 45000

Divide through by 100.

t = 450

Hence, it'll take 450 minutes to empty the pool
