This is what the diagram is saying
(-4)+(-9)= -13
7a-17=4a+1
7a-4a=1+17
3a=18
a=6
ans: a=6
Answer:
Vertical bar graph.
Step-by-step explanation:
A circle graph demonstrates data in the form of percentages that form a circle.
A horizontal and vertical bar graph demonstrate data in the same way, just in different directions.
Answer:
49.8 ft²
Step-by-step explanation:
the picture in the attached figure
given:
a=3, b=1 c=1.8
To know the surface area:
surface area of the figure=surface area of cube+surface area of triangular prism
first lets find out the area of cube and triangular prism.
surface area of cube=4*a²
surface area of cube= 4*3² => 36 ft²
surface area of triangular prism=2*[a*c]+2*[a*b/2] = 2*[3*1.8]+[3*1]
surface area of triangular prism=10.8 +3 = > 13.8 ft²
Therefore, surface area of the figure=36 ft²+13.8 ft²
surface area of the figure= 49.8 ft²
the answer is:
49.8 ft²
