Answer:
84
Step-by-step explanation:
let a be the 1's digit and b the 10's digit, then
a = 2b ← twice the 10's digit, thus
sum = 2b + b = 12, that is
3b = 12 ( divide both sides by 3 )
b = 4
and a = 2b = 2 × 4 = 8
The 2 digit number is 84
Pairs of corresponding angles have the same measure.
Answer:
$15
Step-by-step explanation:
Assuming all the payments are the same, simply divide the total with the amount of payments:
45/3 = 15
$15 each payment.

Answer:
(x+3) and (x-6) are factors
Step-by-step explanation:
The given expression is :
x²-3x-18
We need to find the factors of the above expression.
We can solve it using middle term splitting. We find two integers such that there product is -18 and sum is -3. These two numbers can be -6 and 3.
x²-3x-18 = x²-6x+3x-18
= x(x-6)+3(x-6) [taking common terms]
= (x+3) (x-6)
Hence, the factors of the above expression is (x+3) and (x-6).
X= -6
