Pani-rosa [81]3 years ago
3 0
Answers:
1) A
2) -3

Work:
1) The answer is A because there is a common difference of 2.5 between each term, meaning that exactly 2.5 is added between each successive term of the sequence. 
2) The answer is -3 because in order to get from one term to the next in the above sequence, you must subtract 3. For instance, 11-3=8, 8-3=5, and so on. Since you are subtracting the value must be negative, giving you -3.

If △NMO ∼ △XYZ, and the area of △NMO is 147 square feet, find the area of △XYZ
sladkih [1.3K]

The area of △XYZ according to the figure is 363ft²

<h3>Area of triangles</h3>

The formula for calculating the area of a triangle is expressed as:

A = 0.5bh

  • b is the base
  • h is the height

<h3>Calculate area of each triangles</h3>

For the triangle  △NMO

Area of  △NMO = 0.5bh

147 = 0.5b(14/12)

147 = 7b/12

7b = 12 * 147

b = 252

b = 252ft

b = 3024in

Get the base of △XYZ

14/3024 = 22/XZ

XZ = 4,752in

Area of △XYZ = 0.5 (4,752)(22)

Area of △XYZ= 52,272in²

Area of △XYZ = 363ft²

Hence the area of △XYZ is 363ft²
