Answers

Answer 1

Answer:

Answer:

Length of rectangle = 18 cm

Width of rectangle = 9 cm

Step-by-step explanation:

Let the length of rectangle be x

$\therefore \: width \: (w) = (1)/(2) x \n \n perimeter \: of \: rectangle = 54 \: cm \n \therefore \:2(l + w) = 54 \n \therefore \:(l + w) = (54)/(2) \n \therefore \:l + w= 27 \n \n \therefore \:x + (1)/(2) x = 27 \n \n \therefore \:(3)/(2) x = 27 \n \n \therefore \:x = 27 * (2)/(3) \n \n \therefore \:x = 9 * 2 \n \n \huge \red{ \boxed{\therefore \:x = 18}} \n \n \implies \: (1)/(2) x = (1)/(2) * 18 = 9$

Hence

Length of rectangle = 18 cm

Width of rectangle = 9 cm

10+-2f^2+-6+7+-2f^2+-9f

Answers

$10+-2f^2+-6+7+-2f^2+-9f = 10-2f^2 -6+7-2f^2 -9f \n\n= -2f^2 -2f^2 -9f+10-6+7= \boxed {-4f^2 -9f +11}$

$10+(-2f^(2))+(-6)+7+(-2f^(2))+(-9f)=10-2f^2+1-2f^2-9f$

$-4f^2-9f+11=-(4f^2+9f-11)$
