I am confused on how to do this
babymother [125]
So, u would start by expanding the bracket and ignoring the 2 at the moment.
(x+9)(x+9)= x^2-18x+81(using the foil method!

Then u would put 2 at the front to get:
2(x^2+18x+81)
= 2x^2+36x+162

lorasvet [3.4K]

Answer:

T.A. = 16√3 units²

Step-by-step explanation:

∵ The four faces are equilateral triangles with side length 4

∵ Area of the equilateral Δ = 1/4 s² √3

∴ T.A. = 4 × 1/4 × 4² × √3 = 16√3 units²

For this problem you need to replace x with 45

So the new problem is 2(45)+4

Emmanuel went to the store and
musickatia [10]

Answer:

$148.50

Step-by-step explanation

I solved this by using fractions.

x/450=33/100 is how I set up the problem. 33/100 represents 33%, while x/450 represents how much the jacket costs now.

I then went across and multiplied x by 100, and 450 by 33, which gave me 100x=14850. After this I divided each side by 100 to get 148.5, being the cost of the jacket.

Suzanne has a student loan balance of $25,904 with an average interest rate of 6.8 percent. Use the student loan repayment calcu
Alex_Xolod [135]

Since the problem is requiring us to use the loan repayment calculator and here is what the calculator gave:


Loan Balance: $25,506.00


Adjusted Loan Balance: $25,506.00


Loan Interest Rate: 6.80%


Loan Fees: 0.00%


Loan Term: 10 years


Minimum Payment: $0.00


Monthly Loan Payment: $293.52


Number of Payments: 120 months


Cumulative Payments: $35,223.07


Total Interest Paid: $9,717.07


It is projected that you will need an annual salary of a minimum $35,222.40 to be capable to have enough money to repay this loan. This approximation assumes that 10% of your gross monthly income will be keen to repaying your student loans. This resembles to a debt-to-income ratio of 0.7. If you use 15% of your gross monthly income to repay the loan, you will need an annual salary of only $23,481.60, but you may experience some financial difficulty. This corresponds to a debt-to-income ratio of 1.1.
