To get the area its L x W = A.
So first divide 54 by 9 and you get 6.
9 is your length and 6 is your with.
Perimeter = L + L + W + W or L x 2 + W x 2
9 + 9 = 18 + 6 + 6 = 30 is your answer, so E
Answer:

Step-by-step explanation:
16x2 - 14x
Common factor of 16 and 14 = 2'
for x2 and x it is x,
Answer: 2x.
Answer: factorise the equation 49x^2+70x+25
Step-by-step explanation:
49x^2+70x+25
(7x)^2+2*7x*5+(5)^2
(7x+5)(7x+5)
therefore the sides of the square are (7x+5)(7x+5)
Answer:
Fast train speed: 69 km/h
Slow train speed: 39 km/h
Step-by-step explanation:
Fast train:
-Time: 4.33
-Speed: x
-Distance: 4.33x
Slow train:
-Time: 7.66
-Speed: x - 30
-Distance: 7.66(x - 30)
7.66(x - 30) = 4.33x
7.66x - 229.8 = 4.33x
3.33x = 229.8
x = 69
