Answer: a=−2.3

a+0.3=-2 : a=-2.3

a+0.3=-2 = a=-2.3

Subtract 0.3 from both sides

a+0.3-0.3=-2-0.3

Simplify

a=-2.3

Which expression has exactly three terms? Select all the expressions that apply.
irga5000 [103]

The answer is expressions D, E, and G.

In algebra, a ‘term’ usually means the different parts of an expression that are separated by + and - signs.

Options A and B only have 1 term, an x or y³, so these are incorrect.

Option C has 1 term as well, ‘xyz’, because they are all multiplied together which makes it one term.

D and E both have 3 terms each, but F has 4 unique terms so this is incorrect also.

G has 3 unique terms, x³, x^4, and 7x, so this is correct.

When H is expanded, you will end up with more than 3 unique terms, so this is incorrect.

I hope this helps!
