Answer:
x = 10
Step-by-step explanation:
2) -3x + 17 = -x - 3
4) 20 = 2x
1) -3x + 12 + 5 = -x -3
5) 10 = x
3) 17 = 2x - 3
<u>-3(x - 4) + 5 = -x - 3</u>
<u>-3x + 12 + 5 = -x - 3</u>
<u>-3x + 17 = -x -3</u>
<em>+3x +3x</em>
<u>17 = 2x - 3</u>
<em>+3 + 3</em>
<u>20 = 2x</u>
<u>10 = x</u>

<em>Answer</em><em>:</em>
the surface area of the rectangular pyramid below is 300 units2
11.18
<1 = 50
<2 = 40
<3 = 90
<4 = 90
<5 = 40
<6 = 50
<7 = 130
<5 + <6 = 90
40 + <6 = 90
<5 = <2 because of vertical angles
<6 = <1 because of vertical angles
<7 = <4 + <5
<7 = 90 + 40
