Answer:
C: {−5, 1)
Step-by-step explanation:
Starting with −2|−2x−4|=−12, divide both sides by -2:
|−2x−4| = 6
Reduce this by dividing all terms by 2:
|-x - 2| = 3
This is equivalent to x + 2 = 3 and x + 2 = - 3
Solving thse two equations, we get x = 1 and x = -5
And so the solution set is C: {−5, 1)
width of the rectangle = b = x
length of the rectangle = l = 8 + 2x
Perimeter of the rectangle = 70cm
Also, perimeter of the rectangle = 2(l + b)
70 = 2[x + (8 + 2x)]
70 = 2(x + 8 + 2x)
70 = 2(3x + 8)
70 = 6x + 16
70 - 16 = 6x
54 = 6x
54/6 = x
9 = x
Therefore, b = x
b = 9cm
l = 8 + 2x
I = 8 + 2×9
I = 8 + 18
I = 26cm
Since T is the midpoint of PQ, this means that PT and TQ must be equal to each other. Make them equal to each other in an equation.
PT = TQ
4x + 2 = 7x - 7
- Subtract 2 from both sides.
4x = 7x - 9
- Subtract 7x from both sides.
-3x = -9
<u>x = 3</u>
- Now substitute 3 for x into PT.
PT = 4(3) + 2
<h3>PT = 14</h3>
