<span>x/y where x and y are integers and y≠0 (rational)
2x where x is irrational (irrational)
(√2)/y where y is irrational</span> (cannot be determined)
1 yard = 3 feet:
21 feet / 3 ft = 7 yards
12 feet / 3 feet = 4 yards
7 x 4 = 28 square yards
he will need 28 tiles
10x²+15x-70= 5(2x² +3x - 14)= 5(2x+7)(x -2)
(2x+7)(x -2) = 2x²+7x-4x-14 = 2x²+3x-14
correct answer is A
Yes that statement is true :)
Her unit rate is 5 miles per hour.
