HeLp PlEasE What is the factored form of the following expression? 9x2 + 18x + 9 A. 3(x + 3)(3x + 1) B. 9(x + 1)2 C. (9x + 1)(x + 9) D. 3(x + 1)2 help :

Step-by-step explanation:

9x² + 18x + 9

Factor out 9 from the expression

That's

9( x² + 2x + 1)

Using the identity

a² + 2ab + b² = ( a + b)² factor the expression

We have the final answer as

Hope this helps you

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
