if 2x + y = 7, what is the value of y when x = 3?
-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
7(2 + 2x) is 78 when x = 3. = 5,764,801.
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
2 x 6174 2 x 2 x 3087 2 x 2 x 3 x 1029 2 x 2 x 3 x 3 x 343 2 x 2 x 3 x 3 x 7 x 49 2 x 2 x 3 x 3 x 7 x 7 x 7
2 x 2 x 3 x 7 x 7 x 11 2 x 2 x 3 x 3 x 7 The GCF is 2 x 2 x 3 x 7
IF 3X-1=11, WHAT IS THE VALUE OF X 2 + X?
-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
7(2 + 2x) is 78 when x = 3. = 5,764,801.
Prime factors are 2, 2, 2, 3, 7, 7 Factors are any combination of the above, i.e. 2 x 2 = 4 2 x 3 = 6 2 x 7 = 14 3 x 7 = 21 7 x 7 = 49 2 x 2 x 2 = 8 2 x 2 x 3 = 12 2 x 2 x 7 = 28 2 x 3 x 7 = 42 2 x 7 x 7 = 98 3 x 7 x 7 = 147 2 x 2 x 2 x 3 = 24 2 x 2 x 2 x 7 = 56 2 x 2 x 3 x 7 = 84 2 x 2 x 7 x 7 = 196 2 x 3 x 7 x 7 = 294 2 x 2 x 2 x 3 x 7 = 168 2 x 2 x 2 x 7 x 7 = 392 2 x 2 x 3 x 7 x 7 = 588
3(x^2 +7) is the same as 3x^2 + 21 to find the answer of x set an value to the equation
2, 3 and 7 are prime factors of 84. The prime factorization is 2 x 2 x 3 x 7.
2 x 3 x 3 x 7 x 7 = 882 2 x 2 x 2 x 3 x 7 x 7 x 7 = 8232 2 x 2 x 2 x 3 x 3 x 7 x 7 x 7 = 24696, the LCM
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
x-2 and x -7?
In index form, 378 = 2 x 3 x 3 x 3 x 7 = 2 x 33 x 7
If the equation is (5x + 3 - 7) / 2 = 56, than x = 23.2
A question of prime factors... The answer is 2 x 2 x 3 x 5 x 7 = 420 2 x 2 x 3 x 5 x 7 gives us a factor of 2... 2 x 2 x 3 x 5 x 7 and of 3... 2 x 2 x 3 x 5 x 7 and of 4... 2 x 2 x 3 x 5 x 7 and of 5... 2 x 2 x 3 x 5 x 7 and of 6... 2 x 2 x 3 x 5 x 7 and of 7.
