Answer:
x=7
Step-by-step explanation:
<u>If P is the midpoint of XY, then XP = PY:</u>
- 8x - 2 = 12x - 30
- 12x -8x = 30 -2
- 4x = 28
- x= 28/4
- x= 7
Expand the EXPRESSION
9x^2+216x+1296
Answer:
shorter base = 6 yd
longer base = 8 yd
area of playground = 42 yd^2
Step-by-step explanation:
The question tells you that the shorter side is equal to the width, which is 6 yds. The bases of the triangles on either side are 1 yd. Since there are two, add 1 twice to 6 (6+1+1). This gives you 8 yd for the longer base. You're right about the area, just use the trapezoid area formula: 1/2h(a+b).
