Answer:
The surface area of a rectangular prism with length of
15, a width of 9 and a height of 13 is:
894.0000 square units.
not sure
Step-by-step explanation:
To find the surface area, use this rectangular prism surface area
formula:
Surface Area =
[(Length x Width) + (Length x Height) + (Width x Height)] x 2
Example: The surface area of a rectangular prism with length of
3 inches, width of 4 inches, and height of 5 inches:
Surface Area = [(3 x 4) + (3 x 5) + (4 x 5)] x 2
Calculated out this gives a surface area of 94 Square Inches.

Answer:
x = -11
Step-by-step explanation:
−3x + 6 = 39
-3x = 33
x = -11
9x^2+25 is not factorable
Let first number = x then
we have x and 9x and x + 100
x + 9x + x + 100 = 606
11x + 100 = 606
11x = 506
x = 46
so the three numbers are 46, 146 and 414 Answer
