<span>To find this answer, the equation can be broken down into parts. First, "4m" would equal 28 when m is 7. "np" will be 16, in this case, as well (2 * 8). To finalize, the equation now reads "28 + 23 + 16 - 3," which would total to 64.</span>

If there are 50 teenagers at the football stadium

Given the term 3x², select ALL of the like terms listed below. Question 3 options: A.-2x²
atroni [7]

Answer:

A.-2x^2

D.5x^2

E.x^2

Step-by-step explanation:

Like terms must have the same variable, in this case x, and the same exponent, in this case 2. Since the original term is 3x^2, the like terms will be those that contain x^2, regardless of whether their coefficient or sign is different.

Analyzing the options:

A.-2x^2

We have the same variable and the same exponent x^2, so it is a like term.

B. 3x

You have the same variable x but not the same exponent. So it's not a like term of 3x^2

C.3x^3

Same variable x but as in the previous case, the exponent is different, it is a 3 and it should be a 2, so it is not a similar or like term.

D.5x^2

In this option we do have the x^2, so it is a like term of  3x^2

E.x^2

It is also a like term because it contains the x^2.

In summary the like terms are:

A.-2x^2

D.5x^2

E.x^2

If a car travels 120 miles in 2 hours, what is its rate of speed expressed as a unit rate?​
erastovalidia [21]

The speed is 60 miles per hour

Step-by-step explanation:

Speed is the distance covered per unit time.

The formula for speed is:

Speed = \frac{distance}{time}\\

Given

Distance = d = 120 miles

Time = t = 2 hours

Putting the values in the formula

s = \frac{d}{t}\\=\frac{120}{2}\\= 60

The speed is 60 miles per hour

Keywords: Speed, distance

Cross multiplication, 3(9+x) = 63
27+3x = 63
3x = 63-27 = 36
x=36/3=12
