to find the sum:
2(3t-4) - (t^2 + 2) - 4t(t-1)
6t - 8 - t^2 - 2 - 4t^2 + 4
6t - 8 - 5t^2 + 2
-5t^2 + 6t - 6
by the sum of roots and product of roots formulae
ax^2 + bx + c
x + y = 
x + y = 
xy = 
xy = 
x - y =
Total = Principal * (1 + rate/n)^n*years where "n" is the number of compounding periods
Total = 9,250 * (1 + .07/52)^52*5
Total = <span>9,250 * (1.0013461538</span>)^260
<span><span>Total = 9,250 * 1.418733571
</span>
</span><span>Total = 13,123.29</span>

So first you would have to add $25+$13.50=38.5 then subtract 38.5-2.68=35.82
Answer:
Step-by-step explanation:
2x+90=7x
2x=7x-90
2x-7x=-90
-5x+-90
x=18
Answer:
a) x=25+0.06y
b)x=25+0.06*30=£26.80
c)x=25+0.06*200=£37
d)x=25+0.06y ; 43=25+0.06y ; 43-25=0.06y ; 18=0.06y ; y=18÷0.06 ; y=300 messages
Step-by-step explanation:
aaaaaa hope theyre correct
