100cm squared = 0.01 metres squared
5x squared
4 m squared 1cm sqaured is equal to 0.0001m squared
1 yd = 3 ft 1 foot = 12 in 1 foot squared = 12 inches x 12 inches 1 foot squared = 144 squared inches 1 yard squared = 3 feet by 3 feet 1 yard squard = 9 squared feet 1 yard squared = 9 squared feet x 144 squared inches 1 yard squared =1296 squared inches 5 yards squared = 1296 squared inches x 5 5 yards squared = 6480 inches squared
196 squared = 38416
The GCF of 15ab and 5b squared is 5b.
The GCF is 5b. 5b squared is 25b or (5 x 5) x b 15b is (3 x 5) x b Therefore; 5 x b in each or 5b is GCF
5b2 = 8b therefore 5b =8 therefore b = 1.6
5a2 - 20ab - 25b2 = 5(a2 - 4ab - 5b2) = 5(a2 - 4ba - 5b2) since -5b*b = -5b2 and -5b + b = -4b, then = 5(a - 5b)(a + b)
b over the square root of 5 The square root of 5b squared is 5b, and the simplified form of the square root of 125 is 5 root 5. The 5s then cancel out leaving b over the square root of 5.
5b + 5b = 2 x 5b
The GCF is 5b.
2a+5b isn't possible the answer is still 2a+5b.
5b-15 = -10
15 = 5b
5b
5b-32
