A half-acre building lot is five times as long as it is wide. What are its dimensions?

Gnoma [55]

we know that

A half-acre is equal to----------> $2,023.43\ m^{2}$

Let

x---------> the length side of the building lot

y--------> the width side of the building lot

A------> Area of the building lot

x=5y-------> equation 1

$A=2,023.43\ m^{2}$

$A=x*y$

$2,023.43=x*y$ --------> equation 2

substitute equation 1 in equation 2

$2,023.43=[5y]*y$

$5y^{2}= 2,023.43\\y^{2}= 404.686\\y= 20.11\ m$

Find the value of x

$x=5y---> x=5*20.11--> x=100.55 m$

therefore

the answer is

the dimensions of the building lot are 100.55 m* 20.11 m

Simplify to create an equivalent expression. −5(1−5k)−4(2k+5)

BabaBlast [244]

Answer:

17 k + -25

Step-by-step explanation:

Simplify the following:

-5 (1 - 5 k) - 4 (2 k + 5)

-5 (1 - 5 k) = 25 k - 5:

25 k - 5 - 4 (2 k + 5)

-4 (2 k + 5) = -8 k - 20:

25 k + -8 k - 20 - 5

Grouping like terms, 25 k - 8 k - 20 - 5 = (25 k - 8 k) + (-5 - 20):

(25 k - 8 k) + (-5 - 20)

25 k - 8 k = 17 k:

17 k + (-5 - 20)

-5 - 20 = -25:

Answer: 17 k + -25
