Answer:

Step-by-step explanation:

x^2 + 2x - 3 = (1)^2 + 2(1) - 3 = 0 for x = 1

                       (2)^2 + 2(2) - 3 = 5 for x = 2

                        (3)^2 + 2(3) - 3 = 12 for x = 3

x^3 + 5 = (1)^3 + 5 = 6 for x = 1

               (2)^3 + 5 = 13 for x = 2

               (3)^3 + 5 = 32 for x = 3

x^2 + 5x + 4 = (1 )^2 + 5(1) + 4 = 10 for x = 1

                       (2)^2 + 5(2) + 4 = 18 for x = 2

                        (3)^3 + 5(3) + 4 = 46 for x = 3

A playground is shaped like a quaderaleteral with all sides 27 feet long, with two angles measures of 65 degrees and two angles
Ksivusya [100]

Answer:

Rhombus

Step-by-step explanation:

Shape of a playground is a quadrilateral

It is given that  all sides of a quadrilateral are= 27 feet

Since all the sides of a quadrilateral are equal that it can be either a rhombus or it can be a square

Two angle are 65° each

And other two angers are 115° each

65°+ 115°= 180°

It forms a co-interior angle

Hence the quadrilateral is a parallelogram

Since all the four sides of parallelogram are equal, than the given figure must be rhombus

Hence, geomatric shape best describes the shape of the playground is Rhombus.

What’s the difference between x and 4 is greater than 10
daser333 [38]

Answer:

There is a whole range of speeds at which you are allowed to drive, not just one. In cases like this where there is more than one correct answer, we use inequalities, not equations, to represent the situation.

Inequalities are mathematical statements that define a range of values. They are easily recognizable because they contain the symbols <, ≤,>, or ≥.
