Question

Which expressions represent the sum of exactly two terms?

Answer 1

Answer: D and B

Step-by-step explanation:

Formula for two terms = a + b

Therefore,

D and B have two terms aka one plus sign

D. a + c

B. m^4 + 6m

The sum of two terms is what we get after adding these two terms.

If you add two positive terms, you put a + sign in between these terms.

$\sf{Example\!\!:a+b}$

If you add two negative terms, you put a - sign in between these terms.

$\sf{Example\!\!:a-b}$ (this is the same as $\sf{a+-b}$)

Let's look at the provided choices to see which one works.

Choice A.

• Provided Expression = $\sf{xy}$
• Does Choice A. work ??

It doesn't, because $\sf{xy\neq x+y}$. In this expression a number x was multiplied by a number y. So this one doesn't check.

One down, three to go.

Choice B.

• Provided Expression = $\sf{m^4+6m}$
• Does Choice B. work ??

It does, because $\sf{m^4+6m\stackrel\checkmark{=}m^4+6m}$. A number m was multiplied by itself 4 times, and then the product of that samee number m and 6 was added to it.

So this one checks.

Choice C.

• Provided Expression = $\sf{3+7s+t}$
• Does Choice C.  work ??

It doesn't. It is indeed a sum, but we need 2 terms, not 3

So this one doesn't work.

Choice D.

• Provided Expression = $\sf{a+c}$
• Does Choice D. work ??

It does, because $\sf{a+c\stackrel\checkmark{=}a+c}$. So Choice D. also works.

Hope that made sense !!
