**Answer:**

X=3

**Step-by-step explanation:**

What you have to do is minus 2 from 11 and you get 9

Now divide 3 into 9 and you get 3

x=3 you can also plug 3 for x to see if the equation is right

**Answer:**

281 ft^2

**Step-by-step explanation:**

We need to add each individual 2d shape together to find the surface area

Bottom: 5*12 = **60**

Left side and right side: 4*5 = 20, 2 sides so 20*2= **40**

Side facing us and side facing away from us: 12*4 = 48, 2 sides so 48*2=**96**

Top side that is cut by base of triangle: 7*5 = **35**

Each triangle face: base = 5 (12-7), height = 5 1/2base * height so each triangle is .5*5*5 = 12.5; 4 triangles so 12.5*4=**50**

**60+40+96+35+50=281**

<span>This construction uses Constructing the Perpendicular Bisector of a Line Segment to find the midpoints of the sides.

</span>To construct a midsegment, find the midpoint of two sides. This can be done by drawing a perpendicular bisector on one side of the triangle<span>.
