A builder wants to build a bridge whose cross section is 55ft 6in wide an equation to find the distance b in feet between each beam Is...

An equation is used to represent expressions with equal values. The equation to find the value of b is:

Given that:

To get the value of distance b, we simply add up the length of every item that makes up the cross-section.

So, we have:

Collect like terms

Substitute

Convert inches to feet

Collect like terms

Divide both sides by 5

Hence:

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.
