Step-by-step explanation:

All of the other options are like terms.

Option A: -x+3x=2x

Option B: 4a+7a=11a

Option D. 3p^2q+(-p^2q)=2p^2q

Option C: These terms are not like terms since 2mn is not squared while mn^2 is squared.

Hence,

Answer:

The thrid option or 2mn and mn^2

A volume of a cylinder is given by the expression 6n2 – 13n – 28. The area of the base is 3n + 4.
olga nikolaevna [1]
Volume of cylinder = Base Area x Height

Height = Volume/Base

Height = (6n² -13n -28)/(3n+4)
Perform this division and you will get Height = 2n-7

Given the function f(x)=x2+2x+1, find:<br><br> f( (2a−3)/5 ) =<br><br> Show working please!
Rina8888 [55]
<h3>Given</h3>
  • f(x) = x² + 2x + 1
<h3>Find</h3>
  • f((2a-3)/5)
<h3>Solution</h3>

It can be convenient to rewrite f(x) as a square, then do the substitution. That way, the algebra is simplified a little bit.

... f(x) = (x +1)²

... f((2a-3)/5) = ((2a-3)/5 +1)² = ((2a -3 +5)/5)²

... = (2/5(a+1))²

... f((2a-3)/5) = (4/25)(a² +2a +1)
