30/40 say no, so x/1000 would say no. 1000/40=25, 25*30=750. So, about 750 would dislike it.

This question may be trick question xD haha.

Anyways, a right triangle is a triangle with a right angle (90 degrees). In your picture, that triangle is a right triangle, but the sides could be a bit slanted. Please take a picture from top view, so I can see it properly.

The triangle's length does not matter in this case. As long as it has a right angle, it's a right triangle.

What is the answer to thiss
lana [24]

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression.  So let's plug in the values and solve.

<u>Plug in the values</u>

  • m^2 + 5
  • (9)^2 + 5

<u>Factor out the exponent</u>

  • (9*9) + 5
  • 81 + 5

<u>Combine</u>

  • 86

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.
