Answer:
Correct choice is C). mn=ac
Step-by-step explanation:
Given statement is that the first step in factoring a trinomial of the form is to find two numbers, m and n, such that m + n = b and _____.
We know that when we factor polynomial of type ,product of both numbers m and n must be same as product of a and c.
Hence correct choice is C). mn=ac
Answer:
15.
Step-by-step explanation:
15 is composite because 3 * 5 = 15.
The others are prime.
Answer:
mAB = 49
mABC = 253
mBAC= 156
mACB = 311
Step-by-step explanation:
y = 3p+85, because they are vertical angles.
x = 2p ‐ 10, because they are vertical angles too.
