Answer:
Step-by-step explanation:
x^2 + 2x - 3 = (1)^2 + 2(1) - 3 = 0 for x = 1
(2)^2 + 2(2) - 3 = 5 for x = 2
(3)^2 + 2(3) - 3 = 12 for x = 3
x^3 + 5 = (1)^3 + 5 = 6 for x = 1
(2)^3 + 5 = 13 for x = 2
(3)^3 + 5 = 32 for x = 3
x^2 + 5x + 4 = (1 )^2 + 5(1) + 4 = 10 for x = 1
(2)^2 + 5(2) + 4 = 18 for x = 2
(3)^3 + 5(3) + 4 = 46 for x = 3
actually i still think its the second answer
Ok so firstly the answer is: 361
but here is a arw by step solution
3(7+4)^2-14/7
add 7 and 4 to get 11
3 x 11^2 - 14/7
calculate 11 to the power of 2 (121)
3 x 121 - 14/7
multiply 3 and 121 to get 363
363 - 14/7
divide 14 by 7 to get 2
363-2
subtract the two and you get 361
The answer to question 1 is $8.10.
I got this by finding 18% of $45, which I assume is what the server's tax/tip is.
The answer to question 2 is 7.99.
I got this by finding 8.5 percent of 94 dollars, which is the tax.
Hope this helps, if not, comment below please!!!
