w/7 + 2 = 1
<em><u>Subtract 2 from both sides.</u></em>
w/7 = -1
<em><u>Multiply both sides by 7.</u></em>
w = -7
The value of w is equal to -7
Answer: 81
To get this answer, you do two things
1) Take half of the x coefficient 18 to get 9
2) Square the result from the previous step to get 9^2 = 9*9 = 81
This value is added on to get x^2+18x+81 which factors to (x+9)^2 confirming we have a perfect square trinomial
X= 24 because 26/13 is 2 and 48/24 is also 2
10.3 = 0.6y...divide both sides by 0.6
10.3 / 0.6 = y
17.17 = y <=
It would be be because they didn’t distribute the 8n to the 20
