Hi!
(x+a)·(x+b) = x²+xa+xb+ab = x²-12x-45
x² = x²
xa+xb = (a+b)x = -12x ⇒ (a+b) = -12
ab = -45
When (a+b) = -12 and ab = -45?
+3-15 = -12 and (+3)(-15) = -45
-3-15 = -18 and (-3)(-15) = +45
+3+15 = +18 and (+3)(+15) = +45
-3+15 = +12 and (-3+15) = -45
Answer:
(x+3)(x-15)
Answer:
See my explanation!!!
Step-by-step explanation:
1. M is the midpoint of CD; MD = 3 1. Given
2. MD=CM 2. Definition of Midpoint
3. CM=3 3. If they are equal to each other, then their value equals
Is 12 I think so !! try it
Answer:
It will depend whether is function time dependent or not.
Step-by-step explanation:
If the function is time dependent, the function with greatest initial values continue to be greatest as time increases.
So,
"double 2"
2(2)
"add 5"
+ 5
Therefore, the whole expression would be:
2(2) + 5
If you wanted to evaluate it, it would come out like this.
4 + 5
