Answer:
Step-by-step explanation:
4^(4-7+1) = 4^-2
164.38 = (1 x 100) + (6 x 10) + (4 x 1) + (3/10) + (8/100)
27.99x.075= 2.09925 or 2.10 Rounded
27.99+2.10= $30.09
First I'd expand the brackets so that you can re-simplify the values, so:
(2x + 3)(3x + 4)
6x^2 + 9x + 8x + 12
6x^2 + 17x + 12
The answer A. 2x(3x + 4) + 3(3x + 4) can be simplified the same way, with 6x^2 + 8x + 9x + 12, and so the answer is A. I hope this helps!
