Answer:
Step-by-step explanation:
$18-$7.50= $10.50
MB=(1/2)AB
(1/2)126=63
63=8x+7
56=8x
x=7
<u>We are given the equation:</u>
(a + b)! = a! + b!
<u>Testing the given equation</u>
In order to test it, we will let: a = 2 and b = 3
So, we can rewrite the equation as:
(2+3)! = 2! + 3!
5! = 2! + 3!
<em>We know that (5! = 120) , (2! = 2) and (3! = 6):</em>
120 = 2 + 6
We can see that LHS ≠ RHS,
So, we can say that the given equation is incorrect
Answer:
k = 4
Step-by-step explanation:
In the equation: x² - 2x - 24
Replace the x with x + 3
(x+3)² - 2(x+3) - 24
x² + 6x + 9 - 2x - 6 -24
Let's rearrange it
x² + 6x -2x - 24 + 9 - 6
x² - 4x - 21
f(x+3) = x² - 4x - 21
I think the correct answer from the choices listed above is the third option. The expression that is equivalent to −1.3 (−4.9) (−2.6) would be −1.3 (4.9 2.6). Hope this answers the question. Have a nice day. Feel free to ask more questions. Thank you.
