38 = 26x - 7x 38 = 19x (38/19) = x 2 = x
12*13=156
x2+26x = 68 Completing the square: (x+13)2-169-68 = 0 (x+13)2-237 = 0 x+13 = -/+ sq rt 237 x = -13-/+ sq rt 237
y=2x/6 26=2x/6 26x6=156. 156/2=78. x=78
There are 3 feet in 1 yard, so 156 yards equals 156 x 3 feet, which is 468 feet.
26x-4 = 25 +4 +4 26x = 29 x= 29/26 or 1.115...
38 = 26x - 7x 38 = 19x (38/19) = x 2 = x
12 x 13 = 156
x2+26x = 68 x2+26x-68 = 0 (x+13)2-68 = 0 (x+13)2-169-68 = 0 x+13 = +/- the square root of 237 x = -13 +/- the square root of 237
26x + 9 = 699Subtract 9 from each side:26x = 690Divide each side by 26 :x = 690/26 = 26 and 14/690 = 26 and 7/345 = 26.5385 (rounded)
x2 + 26x + 48 = (x + 24)(x + 2)
To find the number that, when multiplied by 3, equals 156, you would set up the equation 3x = 156, where x is the unknown number. To solve for x, you would divide both sides by 3: x = 156 / 3. Therefore, the number that, when multiplied by 3, equals 156 is 52.
To find two numbers that multiply to 156, we can factorize 156 into its prime factors: 2 x 2 x 3 x 13. Then, we can pair these factors to find the pairs that multiply to 156. The pairs are 1 x 156, 2 x 78, 3 x 52, 4 x 39, 6 x 26, and 12 x 13.
1 x 156, 2 x 78, 3 x 52, 4 x 39, 6 x 26, 12 x 13.
15 times 10 equals 150, so to find the remaining 6, divide 6 by 15 which equals 0.4. Therefore, 15 multiplied by 10.4 equals 156.
12*13=156
The x-axis is y = 0 → y = 8x² - 26x + 15 → 0 = 8x² - 26x + 15 = (4x - 3)(2x - 5) So 4x - 3 = 0 → 4x = 3 → x = ¾ = 0.75 or 2x -5 = 0 → 2x = 5 → x = 2½ = 2.5 The y-axis is x = 0 → y = 8x² - 26x + 15 = 8 × 0² - 26 × 0 + 15 = 15 → The points of contact with the x- and y- axes of y = 8x² - 26x + 15 are: (0.75, 0), (2.5, 0), (0, 15)
