⦁ Rectangle 1 has length, x, and width, y. Rectangle 2 is made by multiplying each dimension of Rectangle 1 by a factor of k, where . ⦁ Are Rectangle 1 and Rectangle 2 similar? Why or why not? ⦁ Write a paragraph proof to show that the perimeter of Rectangle 2 is k times the perimeter of Rectangle 1. ⦁ Write a paragraph proof to show that the area of Rectangle 2 is times the area of Rectangle 1.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
