The answer is 7 because it’s 7
The surface area of the composite figure is 144 square cm after calculating separately.
<h3>What is a triangular prism?</h3>
When a triangle is, stretch it out to produce a stack of triangles, one on top of the other. A triangular prism is the name given to this novel 3D object.
We have a composite figure made up of a triangular prism and a cuboid
First we calculate the surface area of the triangular prism:
= 2(area of one triangle) + area of three rectangles
= 2[(1/2)6×4] + 3×5 + 3×5
= 24 + 15 + 15
= 54 square cm
Surface area of rectangle(with three faces) = 2(4×3 + 4×6) + 3×6
= 2(12 + 24) + 18
= 72 + 18 = 90 square cm
Total surface area of figure = 54+ 90 = 144 square cm
Thus, the surface area of the composite figure is 144 square cm after calculating separately.

Answer:
x=1 or 0
Step-by-step explanation:
because if X is 1 then 3*1 is 3 and 3+2 is five then it's bigger than -10 and smaller than 8
0*3 is 0 then 0 plus 2 is 2 which also works
Expanded form is like this 300 plus 20 plus 7 plus .40 plus .6
