Answer-
10
Explanation-
25% x 4= 100%
And
10 x 4 = 40
Answer:
4
Step-by-step explanation:
This expression is a difference of squares.
(√3 + i)(√3 - i) = (√3)²-(i)², which is
3 - (-1)
= 3 + 1
= 4
Paralell ines have same slope
perpendicular lines have slopes that multiply to -1
y=mx+b is slope intercept
m=slope
b is irrelivant for this problem
solve for y first
5x+7y=12
7y=-5x+12
y=-5/7x+12/7
paralell is same slopoe but differnt b
y=-5/7x+b
sub (5,2)
(x,y)
2=-5/7(5)+b
2=-25/7+b
29/7=b
y=-5/7x+29/7
perpendcular
-5/7 times what=-1
what=7/5
y=7/5x+b
(5,2)
2=7/5(5)+b
2=7+b
-5=b
y=7/5x-5
To solve for this you have the find the density.
D = mass/volume
North side:
D = 36/225
D = 0.16
South side:
D = 37/275
D = 0.13
I think that answer would be neither side.
Hope this helps :)
