Answer:
1. 20x+40
2. 6f+6g
3. 77-28x
Step-by-step explanation:
<u>Use distributive property for all</u>
1) 10(2x+9)-50
20x+90-50
20x+40
2) 6(f+g)
6f+6g
3) 77-28x
4) 3.2(5w+3)
16w + 9.6
25 = -16t^2 + 50t + 4
16t^2 - 50t + 21 = 0
16t^2 - 8t - 42t + 21 = 0
8t(2t - 1) - 21(2t - 1) = 0
(8t - 21)(2t - 1) = 0
8t - 21 = 0 or 2t - 1 = 0
t = 21/8 or t = 1/2
t = 2.625 or t = 0.5
