x2 - 10x + 25 = 64 Or x2 - 10x + 25 = 64?
If the first, move all over to 1 side; x2 - 10x + 25 - 64 = 0
x2 - 10x + -39 = 0
Then make it into quadratic equations; (x - 13)(x + 3) = 0
Therefore x = 13 or x = -3.
If the second, 8x = -39
-39/8 = -9.75 = x
x=-.25.
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
x = 25 / 3squared + 5
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
5n+15 = 25 5n = 25-15 5n = 10 n = 2
x=-.25.
25-7=18 18/3=6
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
x = 25 / 3squared + 5
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
5n+15 = 25 5n = 25-15 5n = 10 n = 2
32 + x = 259 + x = 25x = 25 - 9x = 16
a/5 + 3 = 8 a/5 = 5 a = 25
9+6x = 25-2x 6x+2x = 25-9 8x = 16 x = 2
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
