From the sum of polynomials 3a2−ab−2b2 and 2a2+5ab−3b2 subtract polynomial a2−3ab−4b2.
malfutka [58]

Answer:

4a^2+7ab-b^2

Step-by-step explanation:

First, we will sum

3a^2-ab-2b^2

and

2a^2+5ab-3b^2

Then, from that sum, we will SUBTRACT  a^2-3ab-4b^2

First, lets take the sum by combining like terms:

(3a^2-ab-2b^2)+(2a^2+5ab-3b^2)=5a^2+4ab-5b^2

Now, lets do the subtraction:

(5a^2+4ab-5b^2)-(a^2-3ab-4b^2)\\=5a^2+4ab-5b^2-a^2+3ab+4b^2\\=4a^2+7ab-b^2

This is the answer.

netineya [11]

Answer: 0.0993

Step-by-step explanation:

Since the jar contains 18 red marbles and 38 blue marbles, the total marbles will be:

= 18 marbles + 38 marbles

= 56 marbles

When 2 marbles are pull out at random at the same time, the probability that both are red will be:

= (18/56) × (17/55)

= 0.3214 × 0.3091

= 0.0993
