Answer:
x=−3 or x=5
Step-by-step explanation:
x2−2x−15=0
Step 1: Factor left side of equation.
(x+3)(x−5)=0
Step 2: Set factors equal to 0.
x+3=0 or x−5=0
x=−3 or x=5
The correct answer is A: 3. This is because...
3 * 4 = 12
12 * 5 = 60
Therefore, the answer is 60.
Answer: (14 , 15/2)

...
Answer:
x=8
Step-by-step explanation:
3(x-10)=-6
3x-30=-6
3x=24
x=8
Question 4:
OOOOOHHH a breakthrough! I was confused when I read this question but now I get it!
Okay when dividing this equation I would do this
5^4
25
Since 25 is 5 x 5 I would mark it as 5^2, and then I can subtract!
5^4
5^2 =
5^2
If you do it like this then it would be the first choice.
