It's not an integer because integers must be positive in order to be rational integers. It can still be considered an integer in some cases, but typically you dount count numbers using negatives, do you?

What is the surface area of the triangular prism?<br><br> I need answer ASAP
Nezavi [6.7K]

Answer: 81 ft^2

Hello! The surface area of the rectangular prism will follow this process:

Right triangle area: (1/2)bh

So that 6ft (4.5ft) = 27ft^2/2; though when one multiplies that by 2 (as there are two right triangles), we get a surface area of 27ft^2.

For the rectangle's area, it's slightly more deviated since each face is different in length: bh

Face 1 = 3ft(7.5ft) = 22.5ft^2

Face 2 = 3ft(6ft) = 18ft^2

Face 3 = 4.5ft(3ft) = 13.5 ft^2

Thus, if we add these all together (27ft^2. + 22.5ft^2 + 18ft^2 + 13.5 ft^2), we get 81 ft^2

−8−2y−14x=0

add 14x to both sides

−14x−2y−8+14x=0+14x

−2y−8=14x

Add 8 to both sides.

−2y−8+8=14x+8

−2y=14x+8

Divide both sides by -2.

-2y=14x+8 / -2

y=−7x−4





y=−7x−4
