The perimeter of a rectangle is equal to the sum of its sides.If the length of a a rectangle is twice its width and the perimete

8_murik_8 [283]

Answer: the width of the rectangle

= 31feet.

Step-by-step explanation:

Perimeter of a triangle = 2( l + b)

let the width = xfeet

The length = 2x feet.

Substitute for this in the equation above,

2( 2x + x ) = 186

2(3x) = 186

Divide by 2 through

3x = 93

Divide by 3

x = 31feet. Therefore, the width of the rectangular = 31feet.

Check.

Since the length is twice the width,

L = 31 x 2

= 62feet.

Put that into the formula above

2( 62 + 31 )

2 x 93

= 186 which is the perimeter of the rectangle.

Esplain how to find 30×80 using mental math

Artemon [7]

You ignore the 0's for now and think of 3 x 8 instead
3 x 8 = 24
with the answer of 24, you would now attach the two 0's
2400
2400 is your answer

5. Verify the property a× (b-c)= a×b-a×c for each of the following: a= -3\5; b= 5\9; c= -10\3

ohaa [14]

Answer:

We conclude that

$a\times \left(b-c\right)=\:a\times b-a\times c$

$-\frac{7}{3}=-\frac{7}{3}$

L.H.S = R.H.S

Step-by-step explanation:

Given the property expression

$a\times \left(b-c\right)=\:a\times b-a\times c$

Given that:

a = -3/5

b = 5/9

c = -10/3

Determining the LEFT-HAND SIDE

$a\times \left(b-c\right)$

substituting a= -3/5, b= 5/9 and c= -10/3

$a\times \left(b-c\right)\:=\:\:-\frac{3}{5}\times \left(\frac{5}{9}-\left(-\frac{10}{3}\right)\right)\:\:\:\:\:\:\:\:\:\:\:\:$

$=-\frac{3}{5}\times \:\left(\frac{5}{9}+\frac{10}{3}\right)\:\:\:$

$=-\frac{3}{5}\times \frac{35}{9}$

$=-\frac{7}{3}$

Determining the RIGHT-HAND SIDE

$\:a\times \:b-a\times \:c$

substituting a= -3/5, b= 5/9 and c= -10/3

$\:a\times \:b-a\times \:c=ab-ac$

$=-\frac{3}{5}\left(\frac{5}{9}\right)-\left(-\frac{3}{5}\right)\left(-\frac{10}{3}\right)$

$=-\frac{3}{5}\cdot \frac{5}{9}-\frac{3}{5}\cdot \frac{10}{3}$

$=-\frac{15}{45}-\frac{30}{15}$

$=-\frac{1}{3}-2$

$=\frac{-7}{3}$

Apply the fraction rule: $\frac{-a}{b}=-\frac{a}{b}$

$=-\frac{7}{3}$

Therefore, we conclude that

$a\times \left(b-c\right)=\:a\times b-a\times c$

$-\frac{7}{3}=-\frac{7}{3}$

L.H.S = R.H.S
