Answer:

x = 2/3 or x = -2/5

Step-by-step explanation:

15x^2 - 4x - 4 = ?

factor the left side of the expression and set factors equal to zero:

(3x-2)(5x+2)=0

3x - 2 =0 or 5x + 2 =0

3x =2 or 5x = -2

x = 2/3 or x = -2/5

Answer:

x = 12

perimeter = 124

Step-by-step explanation:

The midline RS is half the length of MN, so we have ...

2×RS = MN

2(x +3) = 5x -30

2x +6 = 5x -30

36 = 3x . . . . . . . . . add 30-2x

12 = x . . . . . . . . . . divide by 3

The length RS is then ...

RS = x +3 = 15

and the perimeter of QRS is ...

P(QRS) = QR +RS +SQ = 25 +15 +22 = 62

The perimeter of QRS is half the perimeter of MNP, so ...

P(MNP) = 2×P(QRS) = 2×62 = 124

The perimeter of ΔMNP = 124.
