HELPPP PLEASE 20 POINTS<br> What is the surface area of this design?
gizmo_the_mogwai [7]

Answer:

197

Step-by-step explanation:

You have 6 sides of this object. So we will calculate six surface areas.

P1=5x5=25 ( on the top)

P2=9x5=45 ( on the bottom)

P3= 5x5= 25 (left side)

P4=6,4x5=32 (rightside)

P5= (9+5)x5/2=70/2=35 ( front trapeze)

P6=P5=35 ( behided trapeze)

P= p1+p2+p3+p4+p5+p6=

25+45+25+32+35+35 =197

9.<br><br><br>A. (3, 6)<br><br>B. (20, –4)<br><br>C. (10, –1)<br><br>D. (–1, 8)
crimeas [40]

Answer:

(10, –1)

Step-by-step explanation:

[1]XXXX3y=−12x+2

[2]XXXXy=−x+9

While it is not technically necessary, I find it easier to clear the fractions before actually beginning; so multiplying [1] by 2

[3]XXXX6y=−x+4

Substituting (from [2]) (−x+9) for y in [3]

[4]XXXX6(−x+9)=−x+4

Simplifying

[5]XXXX−6x+54=−x+4

[6]XXXX5x=50

[7]XXXXx=10

Substituting (from [7]) 10 for x in [2]

[8]XXXXy=−10+9=−1
