Juan is decorating a bulletin board in his classroom. He wants to put a piece of ribbon along the outer edge of the entire board.
If the bulletin board looks like the picture below, how many
inches of ribbon will he need to do the job?
32 inches
48 inches
80 inches
B
А
60 inches
C 160 inches
D
208 inches

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
