2 x 7 = 14 3 x 7 = 21 2 x 3 x 5 = 30

9 x 14 x 30 = 11340

No. x-14 = 17 means x = 31. Add 14 to both sides of the equation to see this.

420 square feet (14 x 30 = 420).

17/20 x 3/3 = 51/60 14/30 x 2/2 = 28/60 so 14/30 is smaller

hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210

2 x 7 = 14 3 x 7 = 21 2 x 3 x 5 = 30

x - x2 - 9x + 14 = 0 ; whence, x2 + 8x = 14 , x2 + 8x + 16 = 30 , and x + 4 = ±√30 . Therefore, x = ±√30 - 4 .

9 x 14 x 30 = 11340

2 x 7 = 14 2 x 3 x 5 = 30 2 x 3 x 5 x 7 = 210, the LCM

If you mean: x = 16 and y = 14 then x+y = 30

If we call the two numbers x and y, we know thatxy = -420andx + y = 16.Solving the second equation for y and substituting it into the first,...y = 16 - xx(16-x) = -420-x² + 16x + 420 = 0x² - 16x - 420 = 0Substituting a, b and c into the quadratic equation and solving for x yeilds -14 and 30. Replacing x with -14 in either equation makes y = 30, and replacing x with 30 in either equation makes y = -14, so the two numbers are -14 and 30.Or, you can look at the factors of 420 (2 x 2 x 3 x 5 x 7), then try combining them to find two that have a difference of 16.Since the product is negative, the two numbers must have opposite signs, therefore you're looking for a difference: 30 = (2 x 3 x 5) & 14 = (2 x 7); 30 x 14 = 420, and 30 - 14 = 16, so the two numbers are 30 and negative 14.

Call the unknown number x. Also note 30 % = 0.30. Then, 0.30x = 14; x = 14/0.30 = 47, to the justified number of significant digits.

No. x-14 = 17 means x = 31. Add 14 to both sides of the equation to see this.

One stone is 14 lbs. Thus 14 X 30 equals 420 lbs.
