2.<br>Remove the brackets and simplify <br>a) (x + 1) + (x + 2)?

devlian [24]

Step-by-step explanation:

✲ $\text{(x + 1) + (x + 2)}$

Remove the unnecessary brackets :

⇢ $\text{x + 1 + x + 2}$

Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

⇢ $\text{x + x + 1 + 2}$

⇢ $\text{2x + 3}$

$\red{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \underline{ \tt{2x + 3}}}}}}}$

Hope I helped ! ♡

Have a wonderful day / night ! ツ

Eunique scores 20 points during the game. This is eleven more than three-fifths of the points she scored in previous game. How m

Ket [755]

Answer:

Step-by-step explanation:

If we call the points she scored in the last game x, we can actually write out an equation to describe what is being said. 20=11+(3/5)x. Hopefully that makes sense. 3/5 of the previous score plus 11 is 20. Anyway, you can just solve this algebraic expression for x.

20=11+(3/5)x subtract 11 from both sides

9 = 3/5 x Multiply both sides by 5

45 = 3x then divide both sides by 3

15 = x And there you go.
