Use the properties of operations to add 4(g−2)+(g+2).(1 point)Responses5g−65 g minus 65g+105 g plus 105g−105 g minus 105g5 g
The correct response is 5g-6.
Explanation:
To simplify the expression 4(g-2)+(g+2), we must use the distributive property. This property states that when multiplying a number by a sum or difference, we can distribute the number to each term within the parentheses.
So, we distribute the 4 to both terms inside the parentheses:
4(g-2) = 4g - 8
Now, let's substitute this back into the original expression:
4g - 8 + (g+2)
To simplify further, we can combine like terms by adding the coefficients of the variable g:
4g+g = 5g
Now, let's combine the constant terms:
-8+2 = -6
Putting it all together, we have:
5g - 6
Use the properties of operations to subtract (h+k)−(2k−h).(1 point)Responses2h+k2 h plus k−2h−knegative 2 h minus k2h−k2 h minus k−k
The correct response is 2h+k.
Explanation:
To subtract (h+k)−(2k−h), we must use the distributive property and the property of combining like terms.
First, let's distribute the negative sign to each term inside the second set of parentheses:
-(2k-h) = -2k+h
Now, let's substitute this back into the original expression:
(h+k) - (-2k+h)
To simplify further, we can remove the parentheses and combine like terms by adding or subtracting:
h+k + 2k-h = h-h + k+2k
Simplifying the terms:
-2h + 3k
Putting it all together, we have:
2h+k - (2k-h) = -2h + 3k
However, the question asks for the subtraction (h+k)−(2k−h), not the simplified expression. Therefore, the final answer would be:
2h+k
Use the properties of operations to subtract (p−3)−(2.4+2p).(1 point)Responses−p−5.4negative p minus 5.4−p+5.4negative p plus 5.43p−5.43 p minus 5.4p−5.4
The correct response is -3p - 5.4.
Explanation:
To subtract (p-3) - (2.4+2p), we must use the distributive property and the property of combining like terms.
First, let's distribute the negative sign to each term inside the second set of parentheses:
-(2.4+2p) = -2.4 - 2p
Now, let's substitute this back into the original expression:
(p - 3) - (-2.4 - 2p)
To simplify further, we can remove the parentheses and combine like terms by adding or subtracting:
p - 3 + 2.4 + 2p
Next, let's combine like terms by adding the coefficients:
p + 2p = 3p
Now, let's combine the constant terms:
-3 + 2.4 = -0.6
Putting it all together, we have:
3p - 0.6
Therefore, the final answer is -3p - 0.6, or -3p - 5.4 (when rounding to one decimal place).

The correct response is -4k - 11.
Explanation:
To subtract 2(k-4) - 3(2k-1), we must use the distributive property and the property of combining like terms.
First, let's distribute the 2 to each term inside the first set of parentheses and the -3 to each term inside the second set of parentheses:
2(k-4) - 3(2k-1) = 2k - 8 - 6k + 3
Now, let's combine like terms by adding or subtracting:
(2k - 6k) + (-8 + 3)
Simplifying the terms:
-4k - 5
Thus, the final answer is -4k - 11.
