Rectangle A and rectangle B are similar.

Mathematics
1 answer:
tamaranim1 [39]2 years ago
5 0

Answer:

82.6 cm

Step-by-step explanation:

First, we make a proportion:

6.2(length A) / 5.6(width A) = 21.7(length B) / x(width B)

Cross multiply: 6.2 * x =( 21.7) * (5.6)

Divide both sides by 6.2: x = 19.6

So the width of rectangle B is 19.6. Now lets find the perimeter

19.6 + 19.6 + 21.7 + 21.7 = 82.6 cm

I hope this helped, please mark Brainliest, thank you!

The equation x2 − 6x − 27 = 0 when solved is:
Amiraneli [1.4K]

Answer:

-3 , 9

Step-by-step explanation:

Sum = - 6

Product = -27

Factors = 3, -9

x² - 6x-27 = 0

x² + 3x - 9x - 9*3 = 0

x(x + 3) - 9(x + 3)  = 0

(x + 3) (x - 9) = 0

x +3 = 0   ; x - 9 = 0

x = - 3     ; x = 9

Solution: x = -3 , 9

True. If you're just changing the form, yes. But remember when you change one side of an equation, you must change the other in the same way.
