Evaluate 5r + d/-3 when r = 6 and d = -6​

32

Step-by-step explanation:

32

Step-by-step explanation:

First substitute d and r with their corresponding substitutions, then solve the expression.

5(6) + (-6)/-3

30 + (-6)/-3

30 + 2

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
