Answer:
x = 11/42
Step-by-step explanation:
2x + 3 = 44x - 8
44x - 2x = 3 + 8
42x = 11
x = 11/42
x = 0.262
Answer:
width: 8.5
length: 4
Step-by-step explanation:
width: x
length: 2x - 13
area = length * width
34 = (2x - 13)x
34 = 2x² - 13x
2x² - 13x - 34 = 0
(2x - 17)(x + 2) = 0
2x - 17 = 0
2x = 17
x = 8.5
x + 2 = 0
x = -2 width cannot be negative so discard this
width: x = 8.5
length: 2x - 13 = 2(8.5) - 13 = 4
Answer:
1).
Sqrt (7 x 12) = 9.165
2).
Altitude = Sqrt (14 x 8) = 10.583
3).
If FG is the angle bisector of angle F in triangle DEF,
DF/EF = DG/EG
6/EF = 4/9
EF = 13.5 in long.
4).
In triangle QRS, XY is parallel to SR.
SX/XQ = RY/YQ
3/2x = 4.5/7.5
9x = 22.5
x = 2.5
The length of QS
= SX + 2x
= 3 + 5
= 8
