Which relationships have the same constant of proportionality between yyy and xxx as the following table?

all of them

step-by-step explanation:

zero eats the zero

it changed by a factor of 2.

the measure of the unknown angle is 7.5

a)  

step-by-step explanation:

we have to remove the roots and then apply exponential formula.

given,

we know,

so, we get

hence the answer is-

the area of the piece of paper =   27- inch square.

so, the length of the square piece of paper = = .

the side of the triangle cut = =

also the side of the small square cut =

so, the area of each triangle cut = 1/2 * .

so, the area of 4 triangles cut =

area of a small square cut =

total area of 4 triangles cut and a small square cut = 6+3 = 9 square inches.

reaming area of the octagonal window   = 27 - 9 = 18 square inches.
