A) (t+s)(x) = t(x) + s(x) = x^3 +4x^2
b) (t*s)(x) = t(x)*s(x) = (x^3)*(4x^2) = 4x^5
c) (t-s)(-1) = t(-1) - s(-1) = (-1)^3 - 4(-1)^2 = -1 -4 = -5
1(4x+7y)+2(5y-9x)
=4x+7y+10y-18x
=-14x+17y
The solution is -14x+17y.
The snail moved 108 inches
108/36=3 yards
as 1 yard=36 in
You multiply .15 times 60 and you get 9 i believe
Distribute: 3x+6+4=5x+7
Simplify: 3x+10=5x+7
Subtract 3x from both sides: 10=2x + 7
Subtract 7 from both sides: 3=2x
Divide by 2: x=3/2
x=3/2
