Answer:

4(2x-y) (2x+y)

Step-by-step explanation:

The area of the picture is 2y*2y = 4y^2

The area of the picture and the frame is 4x*4x = 16x^2

The area of the frame is  The area of the picture and the frame minus The area of the picture

The area of the frame  = 16x^2- 4y^2

Factor out a 4

                                       4(4x^2 -y^2)

This is the difference of squares

a^2 – b^2 = (a + b)(a – b)

a^2 = 4x^2  so a=2x

b^2 = y^2  so b=y

     4(4x^2 -y^2) = 4(2x-y) (2x+y)

Grace invested $5,200 in an account paying an interest rate of 4.6% compounded daily. Assuming no deposits or withdrawals are ma
nlexa [21]

Answer:

Step-by-step explanation:

Use this formula for when compounding is either not continuous or is not annually:

A(t)=P(1+\frac{r}{n})^{(n)(t)} where P is the initial investment, r is the interest rate in decimal form, n is the number of times the compounding occurs per year, and t is the time in years.  For us:

P = 5200,

r = .046,

n = 365, and

t = 11

A(t)=5200(1+\frac{.046}{365})^{(365)(11)} and

A(t)=5200(1+.000126)^{4015} and

A(t)=5200(1.000126)^{4015} and

A(t) = 5200(1.658408042) so

A(t) = $8623.72

In 2020, dawn earned $248,000. social security tax is 6.2% to a maximum income of $137,700. what was your monthly gross pay? in
Dovator [93]

Monthly gross pay is $20,666.67; Dawn reached the maximum taxable social security income in July; the amount of social security tax Dawn paid in February, July and November are $1,281.33, $849.42, and $0 respectively.

<h3>How do we calculate Social Security Tax?</h3>

Annual gross pay = $248,000

Monthly gross pay = $248,000 / 12 = $20,666.67

Maximum taxable social security income = $137,700

Social Security Tax Rate = 6.2%

Total Social Security Tax = Maximum social security income * Social Security Tax Rate = $137,700 * 6.2% = $8,537.40

Monthly Social Security Tax = Monthly gross earnings * Social Security Tax Rate = $20,667 * 6.2% = $1,281.33

Number of months Don reached the maximum taxable social security income = Maximum social security income / Monthly gross pay = $137,700 / $20,666.67 = 6.66 months

Since 6.66 months is greater than 6 but less than 7, this implies that the month Don reached the maximum taxable social security income is the 7th month which is July 2020.

Also, the 6.66 months imply that Dawn will fully pay his Total Social Security Tax in July.

Social security tax Dawn paid in February = Monthly Social Security Tax = $1,281.33

Social security tax Dawn paid in July = Total Social Security Tax - (Monthly Social Security Tax * 6) = $8,537.40 - ($1,281.33 * 6) = $849.42

Social security tax Dawn paid in November = $0

Note that $0 was paid in November because Dawn had already paid fully his Total Social Security Tax in July.

PLEASE HELP!! (Question in picture)<br> For BRAINLIEST and more !!
san4es73 [151]

Like terms are terms that have the same variable no matter the coefficient value such as a negative or positive coefficient (number right to left of the variable aka the letter representing an unknown amount of value).

A. 8n : - 4n becuase the have the same variable (N)

B. - 2d: D because they have the same variable and even if d has no coefficient, it still has value, variables with no coefficient always equal 1 no matter the circumstances

C. - b: 17b and -3b2 because they both have the same variable eliminating the coefficients being two different types of numbers (positive and negative). The expressions have to have the same variable.

D: 4y², -3y2,4y, and 4 to the second power. This is because they all have the same variable.

E. 6x2y: 3xy because the variable are specifially xy and they must be in order to be like terms.

abc: all because they have all the letters but are just in different orders of variables. (thats all)
