2x2 + 6x - 8 = 72 ∴ 2x2 + 6x + 64 =0 ∴ x2 + 3x + 32 = 0 This can not be factored, as x is not equal to any integer. Using the quadratic equation, we find that: x = -3/2 ± √119 / 2i
2*36=72
No. 9 is a factor of 72.
72 centimeters of what. im gonna assume the area is 72 cm. so it would be 72 sq cm your perimeter would be around 33.94 you need to take the squared root of 72. this gives the length of one side. then multiply this number by 4 since there are four sides to a square.
The highest common factor of the numbers 36, 60 and 72 is 12.
x sq equalls 36 and x equalls plus or minus 6
2(x + 6)(x - 6) 2x^2 - 72 = 0 2x^2 = 72 x^2 = 36 x = 6, -6
-9(x + 8)
2(5r + 6)(5r - 6)
22 x 52 x 72 = 702
(7x + 8)(7x - 9)
2x2 + 6x - 8 = 72 ∴ 2x2 + 6x + 64 =0 ∴ x2 + 3x + 32 = 0 This can not be factored, as x is not equal to any integer. Using the quadratic equation, we find that: x = -3/2 ± √119 / 2i
2*36=72
722 = 72 x 72 = 5184
a2 - a - 72 = (a - 9)(a + 8)
5x-72
72 is not a factor of 18; 18 is a factor of 72.
