Solve 2x ≤ 30. Round to the nearest ten-thousandth.
a. {x | x 30.7386)
b. {x|x ≤ 1.9985)
C. {x| ≤ 1.8000)
d. {X/x ≤ 4.9069}

Um i think it is B and i'm gonna be honest i'm not as good with math as i am in reading.

Step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
