Answer:
<u>-2</u>
Step-by-step explanation:
Solving :
3(x + 2) = 5(2x + 4)
3x + 6 = 10x + 20
10x - 3x = 6 - 20
7x = -14
x = <u>-2</u>
Answer:
D. x(x - 7)(x - 5).
Step-by-step explanation:
x3 - 12x2 + 35x
= x(x^2 - 12x + 35)
= x(x - 7)(x - 5).
Answer:
20 Lizard lollies.
Step-by-step explanation:
There are 10 lizard lollis. This is out of 10+4+6 = 20 total treats. This makes the probability of drawing a lizard lollis 10/20 = 1/2.
This means out of 40 treats handed out, we can expect him to give out 1/2(40) = 20 lizard lollis.
Because for input=-2 there are more than one outputs. It means the this is not a function and it’s impossible to find a rule.
