The surface area of rectangular prism is 346 square meters.
Given the figure is rectangular prism.
We know that the surface area of rectangular prism with length L, width W and height H is = 2(LW+WH+LH)
Given that the length of prism = 5 m
Width of prism = 17 m
Height of prism = 4 m
So the total surface area of the rectangular prism is given by,
= 2 [5*17 + 17*4 + 4*5]
= 2 [85 + 68 + 20]
= 2*173
= 346 square meters
Hence the surface area of rectangular prism is 346 square meters.

Let u be the number of used cars and n the number of new cars, then u+n=17.
Sales values: 7000u+16000n=191000; so 7u+16n=191.
Since n=17-u, we can rewrite this: 7u+16(17-u)=191.
7u+272-16u=191, 9u=272-191=81 and u=9. So 9 used cars were sold (8 new).
Answer:
The original number is 
Step-by-step explanation:
Let
x -----> the original number
Remember that
The increased number is equal to multiply the original number by the factor 1.071
so
Solve for x
Divide by 1.071 both sides
Answer:
5y+3x=4
Step-by-step explanation:
The standard form for the equation of a line is Ax+By=C In this case with the equation 5y-4=-3x B=5 and A=-3 and C=-4 in order to get Ax and By on the same side we can add both -4 and -3x to both sides to get this in the correct form and we get 5y+3x=4
I hope this helps and please don't hesitate to ask if there is anything still unclear!
