$\bf 6\sqrt[4]{405}\quad now\to 
\begin{cases}

Rocky needs at least $32 to buy an amplifying speaker. He already has $17. Which graph best represents all the possible dollar a

vitfil [10]

Number line with closed circle on 15 and shading to the right. That's because 32 - 17 = 15 and since you need at least 15 more dollars the circle would be closed and shading to the right since it's at least meaning 15 or more.

The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x. step by step explanation.

Debora [2.8K]

<h3>Question:</h3>

The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x.

<h3>To find:</h3>

Area in terms of x

<h3>Given:</h3>

Perimeter = 30 cm

L = x

<h3>Answer :</h3>

<u>To</u><u> </u><u>find</u><u> </u><u> </u><u>area</u><u> </u><u>first</u><u> </u><u> </u><u>we</u><u> </u><u>should</u><u> </u><u>know</u><u> </u><u> </u><u>value</u><u> </u><u> </u><u>of</u><u> </u><u>with</u><u>.</u>

So first Let's find width by using this formula:

$\blue{\boxed { \sf \underline {Perimeter=2(Length+Width)}}}$

Insert Value of length and perimeter.

$: \implies \sf 30 = 2(x + width)$

$: \implies \sf \dfrac{30}{2} = (x + width)$

$: \implies \sf{}x + width = \dfrac{ { \cancel{30}}^{ \: 15} }{ { \cancel{2}}^{ \: 1} }$

$: \implies \sf{}x + width = 15$

$: \implies \sf{} \star \underline{\underline{ width = 15 - x}} \star$

Now Let's find Area by using this formula

$\blue{\boxed { \sf \underline {Area=Length \times Width }}}$

$: \implies \sf{}Area = x \times (15 - x)$

$: \implies \sf{} \star \underline{\underline{ Area = 15x - {x}^{2} \: cm {}^{2} }} \star$

hope it helps!
