The following steps are used to rewrite the polynomial expression (x + 4y+z)(x-7y). Step 1: x(x - 7y) + 4y(x - 7y) + z(x-7y) Step 2: x2 - 7xy + 4yx - 28y2 + zx - 7zy Step 3: x2 - 7xy + 4xy - 28y2 + xz - 7yz Step 4: r? - 3xy - 28y2 + x2 - 7yz dentify the property used in each of the steps:​

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

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
