hi <3

a) the length would be: 2x + 2 + 1/2x - 4 + x - 2

simplified the length would be: 3.5x - 4

the width would be: x + x - 2

simplified the width would be: 2x - 2

b) the perimeter would be: 3.5x - 4 + 2x - 10 + x - 2 + 1/2x - 4 + x - 2 + 2x - 2 + 2x - 2

simplified this would be: 11x - 26

c) 11x - 26 = 142

add 26 to both sides:

11x = 168

divide both sides by 11:

x = 15.27

hope this helps :)

Avery bought a washing machine originally priced at $864.72 but on sale for 30% off. After 4% sales tax, what was the total cost
atroni [7]

Use the Law of Cosines to find the missing angle. In triangle FGH, HF = 16 ft, FG = 23 ft, and m∠F = 52°. Find the measure of f.
ivolga24 [154]
F = 18 ft.

The law of cosines states 
c² = a² + b² - 2ab cos C

Using our information, we have 
c² = 23² + 16² - 2(23)(16)cos 52
c² = 529 + 256 - 736cos 52
c² = 785 - 736cos 52
c² = 331.8732

Taking the square root of both sides, we have
c = √331.8732 = 18.22 ≈ 18

function :  y = (-x) - 6

<u>Find x-intercept</u> :

  • (-x) - 6 = 0
  • (-x) = 6
  • x = -6

<u>Find y-intercept</u> :

  • y = (-0) - 6
  • y = -6

mark these two points on both the axis and draw a straight linear graph.

passes coordinates : (0, -6), (-6, 0)

vladimir2022 [97]

Answer:

$25

Step-by-step explanation:

We know,

Monthly interest = (Principal × Interest rate) ÷ 12

Given,

Loan principal = $3,000

Interest rate = 10% = 0.10

Therefore, monthly interest = ($3,000 × 0.10) ÷ 12

Monthly interest = $300 ÷ 12

Monthly interest = $25

Therefore, the principal amount to be paid per month is = $(96.80 - 25) = $71.80.

So, Jamison will pay $25 as interest for the 36-month $3,000 loan.
