Answer:
The remainder is 55
Step-by-step explanation:
Let

According to the remainder theorem, if p(x) is divided by x+a, the remainder is p (-a).
The given divisor is x+2, therefore the remainder is given by:

We substitute x=-2 to get:

We simplify to obtain:

We multiply to get:

Therefore the remainder is 55
Answer:
none
Step-by-step explanation:
Answer:
a) 5:3
b) 25:12
c) 1:2
Step-by-step explanation:
a) 20:12 = 20/12 = 10/6 = 5/3 = 5:3
b) 25:12 -> cannot be simplified so -> 25:12 itself
c) 10:20 = 1/2 = 1:2
Answer:
65 = 6x + 7
6x = 58
x = 9.6666666...
65 + y + 9 = 180
y = 106
