Find the composite area
stepladder [879]

Answer:

Area of the composite figure = 42 in²

Step-by-step explanation:

Composite area of the given figure = Area of the rectangle + Area of the right triangle

Area of the rectangle = Length × Width

                                    = 6 × 5

                                    = 30 in²

Area of the right triangle = \frac{1}{2}(\text{Base})(\text{Height})

                                         = \frac{1}{2}(4)(6)

                                         = 12 in²

Area of the composite figure = 30 + 12

                                                  = 42 in²

Lloyd solves the equation 24x + 18(x – 2) = 216 for x. Some of his steps are shown.
Elena-2011 [213]

Answer:

Hi there!

Your answer is:

To get from step 3 to step 4, Lloyd added 36 to both sides. On the left side, this equaled 0 due to the additive inverse property! (-36 + 36 = 0!) On the right side, 36 is added to 216! (216+36 = 252)

Could you please help me with number 6 thank you sm !!
ololo11 [35]

Answer:

  • A) a = 4, b = 3

Step-by-step explanation:

<h3>#6</h3>

<u>Given equation:</u>

  • 4/(x - 3) + 2/(x - 2) = 2

<u>Multiply all terms by (x - 3)(x - 2):</u>

  • 4(x - 2) + 2(x - 3) = 2(x - 3)(x - 2)
  • 2(x - 2) + (x - 3) = (x - 3)(x - 2)
  • 2x - 4 + x - 3 = x² - 5x + 6
  • x² - 5x - 3x + 6 + 7 = 0
  • x² - 8x + 13 = 0
  • x = (8 ± √(8² - 4*13))/2 = (8 ± √12)/2 = (8 ± 2√3)/2 = 4 ± √3

<u>Compare this to the given form to get:</u>

  • a = 4, b = 3

Correct choice is A
