Answer:

Step-by-step explanation:

We are told that Roxanne:

Has a checking account only
Uses online banking
Uses the bank ATM once a month
Uses a nonbank ATM twice a month

We need to work out how much it costs for Roxanne to bank with each bank each month, then compare the total costs to see how much Roxanee could save if she switch from East Median to Jasmine bank.

Cost of monthly banking at East Medina Bank:

Checking account services = $6

Online banking = $5 (remember, she doesn't have a linked savings a/c)

ATM (1 use) = $1

nonbank ATM (2 uses) = $6

Total = $18

Cost of monthly banking at Jasmine Bank:

Checking account services = $10

Online banking = $4

ATM (1 use) = $0

nonbank ATM (2 uses) = $0

Total = $14

To calculate the money Roxanne could save by switching to Jasmine Bank, simply find the difference between the monthly costs:

Savings = $18 - $14 = $4

Answer:

1. y=7.2

2. x=18

Step-by-step explanation:

1. Triangles CMN and CBA are similar triangles (by AAA postulate). Similar triangles have proportional corresponding sides, so

$\dfrac{CM}{CB}=\dfrac{CN}{CA}\\ \\\dfrac{12}{12+y}=\dfrac{10}{10+6}\\ \\12\cdot 16=10\cdot (12+y)\\ \\192=120+10y\\ \\10y=72\\ \\y=7.2$

2. GK is angle G bisector. Use angle bisector's property:

$\dfrac{GH}{GI}=\dfrac{KH}{KI}\\ \\\dfrac{40}{24}=\dfrac{30}{x}\\ \\40x=24\cdot 30\\ \\4x=24\cdot 3\\ \\x=6\cdot 3=18$

Factor completely, then place the factors in the proper location on the grid. x^2n + 10x^n + 16

postnew [5]

Answer:

$(x^n + 2)(x^n + 8)$

Step-by-step explanation:

The polynomial $x^{2n}+10x^n + 16$ can be factored exactly the same as the polynomial $x^2 + 10x + 16$ . Here it factors into two numbers which multiply to 16 but add to 8. These factors are 8 and 2. So it factors into the expression (x+8)(x+2).
