  • Calculation of the discriminant of the polynomial : 18+x+x²
  1. Applying the formula to calculate the discriminant Δ=b²−4 ⋅ a ⋅ c with :     a = 1, b= 1, c = 18
  2. Δ = (1)² − 4 ⋅ (1) ⋅ (18) = 1 −72 = −71  
  3. The discriminant of the polynomial 18+x+x² is equal to −71

What is the area of the actual square window shown in the scale drawing?
larisa86 [58]

The area of the actual square window = 2.25 m².

<h3>Scale Drawing</h3>

Scale drawing relates the actual length of an object to its length on a paper.

Given a scale of 1 in = 2 m, it means 1 in on paper is about 2 m of the actual length of the object.

Thus:

  • Length on scale drawing = 0.75 in
  • Actual length = x

Therefore:

1/2 = 0.75/x

  • Cross multiply

x = 1.5 m

Area of the actual square window = 1.5² = 2.25 m².

The scale in the drawing is 2 cm : 5 m. Select from the drop down the correct numbers into the boxes to give the length, width,
Gelneren [198K]

The length, width, and area will be 25m, 15m, and 375m².

<h3>How to calculate the area?</h3>

From the information given, the scale in the drawing is 2cm : 5m and the length and width are given as 10cm and 6cm respectively.

Length = 10cm = 10 × 2.5 = 25m

Width = 6cm = 6 × 2.5m = 15m

Area = Length × Width

Area = 25 × 15

Area = 375m²

Therefore, the area is 375m².
