Question:

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

To find:Area in terms of xGiven:Perimeter = 30 cmL = xAnswer :

To find area first we should know value of with.

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!

Answer from: Quest

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.

Answer from: Quest

$655.61 which is option c

step-by-step explanation:

price of house = $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

= $\frac{3.5*146000}{100}$

=$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

=$35770

remaining money = $146000-35770

=$110230

new mortgaged payment = 5 % of 110230

= $\frac{5*110230}{100}$

=$655.61
