let x=width, so 2x=length

area = area __ (x+3)(2x+3) = (x)(2x) + 54

2x^2+9x+9 = 2x^2+54

subtracting 2x^2+9 __ 9x = 45

dividing by 9 __ x = 5

In a right –angled triangle, the length of hypotenuse and shorter sides are 13 cm and 5 cm respectively. Work out the other side

stellarik [79]

Answer: The other side is 12 cm.

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$
$a^{2} + (5)^{2} = (13)^{2}$
$a^{2} + 25 = 169$
$a^{2} = 144$
$a = \sqrt{144}$
$a = 12$

To solve for y in the equation 2 x + y = 5, subtract 2 from both sides of the equation.

steposvetlana [31]

Answer:

False.

Step-by-step explanation:

Because we have to isolate y and subtracting 2 will not put y alone on one side.

We have to subtract 2x in order to solve for y.
