Answer:

The sum is a binomial of degree 3.

Step-by-step explanation:

You are adding two binomials. Each binomial has two terms.

The terms 6s^2t and 4s^2t are like terms and combine to give the sum 10s^2t.

The terms -2st^2 and -3st^2 are like terms and combine to give the sum -5st^2.

The sum of the binomials is the binomial 10s^2t - 5st^2.

Since each original binomial is of degree 3, the sum is also of degree 3.

Answer: The sum is a binomial of degree 3.

Answer : The correct option is, (A) 10

Step-by-step explanation :

First we have to calculate the volume of cylinder shaped can.

Formula used:

Volume of cylinder = π r² h

where,

r = radius of cylinder

h = height of cylinder

Given:

Diameter of cylinder = 3 in

Height of cylinder = 6 in

Radius of cylinder = $\frac{Diameter}{2}=\frac{3in}{2}=1.5in$

Now putting all the given values in the above formula.

Volume of cylinder = π r² h

Volume of cylinder = 3.14 × (1.5 in)² × 6 in

Volume of cylinder = 42.39 in³

Now we have to determine the number of soda cans are in a pack.

Number of soda cans are in a pack = $\frac{\text{Volume of soda pack}}{\text{Volume of cylinder shaped can}}$

Number of soda cans are in a pack = $\frac{423.9in^3}{42.39in^3}$

Number of soda cans are in a pack = 10

Therefore, the number of soda cans in a pack are 10.

WILL GIVE BRAINLIEST IF CORRECT

Ivahew [28]

Answer:

The second answer.

Step-by-step explanation:

Tim is correct. Absolute value is just the distance away from 0. In this case, both P and Q are 3/8 away from zero, even though they have opposite signs. In fact, opposites signs of the same number will always have the same absolute value because they are the same distance from 0.

So, it is the second one.

Hope this helps!
