Use the given values of n=2112, p= to find the minimum value that is not significantly 4
low, 1-20, and the maximum value that is not significantly high, +20. Round your
answer to the nearest hundredth unless otherwise noted.
A) Minimum: 1478.7; maximum: 1689.3
B) Minimum: 1544.2; maximum: 1623.8
C) Minimum: 1564.1; maximum: 1603.9
D) Minimum: 1623.8; maximum:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
