Answer:

(5x +4y)^2

Step-by-step explanation:

The first and last terms are both perfect squares, and the middle term is twice the product of their roots. That means the trinomial is the perfect square trinomial ...

25x^2 +40xy +16y^2 = (5x +4y)^2

_____

It matches the pattern ...

a^2 +2ab +b^2 = (a +b)^2

Radius question <br><br> * answers listed on pic but I just need a step by step explanation *

Rama09 [41]

Step-by-step explanation:

Let A(x) be the area function of given rectangle.

Radius of circle = 7x

Therefore, length of rectangle = 14x

Width of rectangle = 7x

$\therefore \: A(x) =l\times w \\ = 14x \times {(7x)} \\ =98x^2 \\ \huge \red{ \boxed{ \therefore \: A(x) =98 {x}^{2} }}$

Let P(x) be the Perimeter function of given rectangle.

$P(x) =2(l + w) \\= 2(14x + 7x)\\=2\times 21x\\= 42x\\\huge \red{ \boxed{ \therefore \:P(x)= 42x}}$
