X squared = x+6 6+x=x squared X=6

(x + 10)/2 = (x - 6)/x. Multiply both sides by 2x to produce: x2 + 10x = 2x - 12 Rearrange and collect like terms to produce: x2 + 8x + 12 = 0 Factoring produces: (x + 6)(x + 2) = 0, which is true whenever x = -6 or x = -2 Check: for x - -6: (-6 + 10)/2 = 2; (-6 - 6)/-6 = -12/-6 = 2 (-2 + 10)2 = 4; (-2 - 6)/-2 = -8/-2 = 4.
1 x 474, 2 x 237, 3 x 158, 6 x 79, 79 x 6 = 474
Hexagon has 6 sides. Each measures 79 cm ⇒ Perimeter = 6 x 79 cm = 474 cm
493,039
7.9 x 10^6
158 = x * 79 158 / 79 = x 2 = x 158 is 200% of 79 ■
x - 56 = 79 x - 56 + 56 = 79 + 56 x = 135
1 x 79
79 x 3 = 237
5 x 79 = 395
79 x 86 = 6974
Only by itself and one because 79 is a prime number
The answer is 79. Since you know the values of x and y, you can simply substitute them into the equation to find the answer. x = 6 y = 7 5x + 7y = 5(6) + 7(7) = 30 +49 = 79
