The answer is 55 + 12t.
12(t+6)+8=4(2t-1)+2t 12t+72+8=8t-4+2t 12t-2t-8t=-72-8-4 2t=-84 2t/2=84/2 t=42
12 (t -6) + 8 4 (2t - 1)Distribute: 12t-72+8 8t-4Combine like terms: 12+-64 8tSubtract 12t from each side: -64 -4tMultiply each side by -1: 64 4tDivide each side by 4: 16 tSo t = 16
12t + 15
Divide all terms by -1: 5t2-12t-9 = 0 (5t+3)(3t-3) = 0 Therefore: t = -3/5 and t = 3 Use the quadratic equation formula.
The answer is 55 + 12t.
-12t+4
It is (3t-2)(3t+2) when factored and it is the difference of two squares
7s plus 8t plus 10s plus 12t can be simplified to 17s plus 20t.
9t2
12t(t2-4) 12t(t-2)(t+2)
12(t+6)+8=4(2t-1)+2t 12t+72+8=8t-4+2t 12t-2t-8t=-72-8-4 2t=-84 2t/2=84/2 t=42
9t2 + 42t + 49 is a perfect square, equal to (3t + 7)2
The answer is 12t.
12 (t -6) + 8 4 (2t - 1)Distribute: 12t-72+8 8t-4Combine like terms: 12+-64 8tSubtract 12t from each side: -64 -4tMultiply each side by -1: 64 4tDivide each side by 4: 16 tSo t = 16
12t + 15
GCF(48t, 60st) = 12t.
