Answer:
4+4m+3p
Step-by-step explanation:
12-m+3p-8+5m
Rearrange the terms
12-8-m+5m+3p
4+4m+3p
<span>X+y=11
Xy=30
</span><span>
x=11-y
(</span>11-y)y=30
11y-y²=30
11y-y²-30=0
y²-11y+30=0
y²-5y-6y+30=0
y(y-5)-6(y-5)=0
(y-5)(y-6)=0
y-5=0
y=5
y-6=0
y=6
x=11-y
x=11-5=6
x=11-6=5
x=6 y=5
x=5 y=6
600 would be the correct answer.
Me (now) : x
5 years ago, me: x - 5
5 years ago, my grandfather: 5.(x - 5)
Now, my grandfather: 5.(x - 5) + 5 = 5x - 25 + 5 = 5x - 20 (I)
Three years from now, me: x + 3
Three years from now, my grandfather: 3.(x + 3) = 3x + 9
Now, my grandfather: 3x + 9 - 3 = 3x + 6 (II)
___________________________________________
Now:
3x + 6 = 5x - 20
26 = 2x
13 = x
So, I am 13 years old. :)
Pi is an irrational number so you cannot find that square root<span />
