Answer:

SUBSTITUTE

☺ Hello mate__ ❤

◾◾here is your answer...

i think right question is this

(3x − 7y)^2

ok now start solving:-

(3x − 7y)^2

=> (3x − 7y) (3x − 7y)

=> 3x(3x- 7y) -7y(3x-7y)

=>. 3x.3x - 3x.7y-7y. 3x + 7y.7y

=> 9x^2 -27xy +27xy + 49y^2

=> 9x^2 + 49y^2

so your correct ans. is 9x2 + 49y2

➽━━━━━━━━━━━━━──➸

I hope, this will help you.☺

Thank you______❤

Evgen [1.6K]

Answer:

The perimeter is P=73.12\ cm

Step-by-step explanation:

we know that

The perimeter of the figure is equal to the circumference of a semicircle

plus the perimeter of a square minus the diameter of the circle

so

P=\pi r+4(b)-D

we have

r=8\ cm

b=16\ cm

D=16\ cm

The diameter of the circle is equal to the length side of the square

substitute

P=(3.14)(8)+4(16)-16

P=25.12+64-16

P=73.12\ cm
