Find the dimension of the figure

USPshnik [31]

Answer:

length = 10 ft, width = 9 ft

Step-by-step explanation:

The opposite sides are congruent

The perimeter (P) = 38 and is the sum of the 4 sides, then

15 - 2x + 15 - 2x + x + 7 + x + 7 = 38 , that is

- 2x + 44 = 38 ( subtract 44 from both sides )

- 2x = - 6 ( divide both sides by - 2 )

x = 3

Then

length = x + 7 = 3 + 7 = 10 ft

width = 15 - 2x = 15 - 2(3) = 15 - 6 = 9 ft

Answer:

$m=\frac{108}{x}$

m=18 mi/day

Step-by-step explanation:

#The distance remaining is:

$d=150-42\\\\=108 \ miles$

Let m be the number of miles per day for the remaining distance and let x be the remaining number of days:

$v=\frac{d}{t}, v-speed, t-time, d-distance\\\\m=\frac{108}{x}\\\\$

#Given that the remaining number of days is 6, we substitute and solve for m:

$v=\frac{d}{t}, v-speed, t-time, d-distance\\\\m=\frac{108}{6}\\\\=18\ mile/day$

Hence her speed per day is 18 mile/day using the inequality $m=\frac{108}{x}$
