Line YZ is the midsegment of triangle QRS because it connects the midpoints of lines QR and RS. We would solve for x by appying the midsegment theorem which states that the midsegment is half the length of the third side or base. This means that

YZ = 1/2(QS)

x + 2 = 1/2 * (3x - 8)

2(x + 2) = 3x - 8

By opening the parenthesis, we have

2x + 4 = 3x - 8

Collecting like terms, we have

3x - 2x = 4 + 8

x = 12

Option C is correct

Bailey writes the expression g2 + 14g + 40 to represent the area of a planned school garden in square feet. If g = 5, what are t

ikadub [295]

The expression is $A=g^2 + 14g + 40$ .
$D=14^2-4\cdot 40=196-160=36 \\ \sqrt{D}=6 \\ q_{1,2}= \dfrac{-14\pm 6}{2} =-4,-10$ .
Then $A=g^2 + 14g + 40=(g+4)(g+10)$ .
The width is g+4, the length is g+10.
When g=5,
g+4=9 ft and g+10=15 ft.
Answer: correct choice is D.
