The combined area of a pair of congruent rectangles can be represented, in square units, by the expression 18y^2-818y 2 −8. The

sveta [45]

Answer:

$Perimeter = 12y$

Step-by-step explanation:

Given

$Area = 18y^2 - 8$ -- two rectangles

Required

Determine the perimeter of one of the rectangles

First, calculate the area (A) of 1 rectangle

$A =\frac{1}{2}Area$

$A =\frac{1}{2}(18y^2 - 8)$

$A =9y^2 - 4$

Express as difference of two squares

$A =(3y - 2)(3y+2)$

Area is calculated as:

$A = Length * Width$

So, by comparison:

$Length = 3y - 2$

$Width = 3y + 2$

The perimeter is:

$Perimeter = 2 *(Length + Width)$

$Perimeter = 2 *(3y-2+3y+2)$

Collect Like Terms

$Perimeter = 2 *(3y+3y-2+2)$

$Perimeter = 2 *(6y)$

$Perimeter = 12y$

Between the time Iko woke up and lunchtime, tue temperature rose by 11 degrees. Then by the time he went to bed, the temperature

Ierofanga [76]

Answer:

$T_b=(x-3)\textdegree$

Step-by-step explanation:

let x° be temperature when he woke up. Given that the temperature rose by 11° then later dropped by 14°. Also let $T_b$ be temperature at time she went to bed.

-We add the temperature rise and subtract the temperature drop to find temperature at time she goes to bed.

-The temperature relative to time of waking up can be expressed as:

$T_b=x\textdegree\pm\bigtriangleup T\textdegree\\\\T_b=x\textdegree+11\textdegree-14\textdegree\\\\T_b=(x-3)\textdegree$

Hence, the temperature relative to the time Iko woke up is (x-3)°
