The length of a rectangular garden is 8 feet longer than its width. The garden's perimeter is 188 feet. Find the length of the g
DaniilM [7]

Step-by-step explanation:

<em>perim</em><em>eter</em><em>=</em><em> </em><em>2</em><em>×</em><em>L</em><em>e</em><em>n</em><em>g</em><em>t</em><em>h</em><em> </em><em>+</em><em> </em><em>2</em><em>×</em><em>w</em><em>i</em><em>d</em><em>t</em><em>h</em>

<em>from</em><em> </em><em>the</em><em> </em><em>qu</em><em>estion</em><em>,</em>

<em>perim</em><em>eter</em><em>=</em><em>1</em><em>8</em><em>8</em><em>f</em><em>e</em><em>e</em><em>t</em>

Length is 8 feet more than the width

which means that

length =8 + Width

substitute them into the question

188 = 2(8+width) +2w

188 =16 +2w+2w

188=16 +4w

solving for W

4w =188-16

(2t-3)^3, can you help me?, please?
grandymaker [24]

Answer:

8t^3-36t^2+54t-27

Step-by-step explanation:

(2t-3)^3

(2t-3)(2t-3)(2t-3)

Multiply the first two terms

(4t^2 -6t -6t+9)(2t-3)

Combine like terms

( 4t^2 -12t +9) ( 2t-3)

Multiply

2t*( 4t^2 -12t +9) -3 ( 4t^2 -12t +9)

Distribute

8t^3 -24t^2 +18t-12t^2 +36t-27

Combine like terms

8t^3-36t^2+54t-27
