Luda [366]

$\text {Hi! Let's Solve this Problem!}$

$\text {The First Step is to Convert all Mixed Numbers into Improper Fractions:}$

$\text {Multiply 5*5 and get 15. Now add 1 and get 16.}\\\text {5 1/3 = 16/3}$

$\text {Multiply 2*5 and get 10. Now add 4 and get 14.}\\\text {2 4/5 = 14/5}$

$\text {Your new Problem should be: 16/3-14/5}$

$\text {The Next Step is to Subtract:}$

$\text {16/3-14/5=}$

$\text {Your Answer would be:}$

$\fbox {38/15}$

$\text {Your Final Step is to Convert 38/15 into a Mixed Number:}$

$\text {38/15=}$

$\text {Your Final Answer would be:}$

$\fbox {2 8/15}$

$\text {Best of Luck!}$

raj and his sister zia are both at secondary school. Raj is three years older than zia. the sum of the squares of their ages is

steposvetlana [31]

Let's assume

Raj's age is x years

Zia's age is y years

we are given

Raj is three years older than zia

so, we get

$x=y+3$

now, we can solve for y

$y=x-3$

the sum of the squares of their ages is 369

so, we get

$x^2+y^2=369$

now, we can plug back y

$x^2+(x-3)^2=369$

now, we can solve for x

$2x^2-6x+9=369$

$2x^2-6x-360=0$

$x^2-3x-180=0$

$(x+12)(x-15)=0$

$x=-12 , x=15$

Since, age can not be negative

so, we will only consider positive

$x=15$

now, we can find y-value

$y=15-3$

$y=12$

So,

Raj's age is 15 years

Zia's age is 12 years...........Answer

Given that a rectangle has a length of 5/2x + 10 with a width of 5/2x + 5, formulate an expression to represents the area of the

stepan [7]

Answer:

<h3> A = ²⁵/₄x² + ⁷⁵/₂x + 50</h3>

Step-by-step explanation:

L = ⁵/₂x + 10

W = ⁵/₂x + 5

A = L•W

A = (⁵/₂x + 10)(⁵/₂x + 5)

A = ⁵/₂x•⁵/₂x + ⁵/₂x•5 + 10•⁵/₂x + 10•5

A = ²⁵/₄x² + ²⁵/₂x + ⁵⁰/₂x + 50

A = ²⁵/₄x² + ⁷⁵/₂x + 50

Or if yoy mean:

L = 5/(2x) + 10

W = 5/(2x) + 5

A = [5/(2x) + 10][5/(2x) + 5] = 25/(4x²) + 75/(2x) + 50
