What is the area, in square meters, of the shaded part of the rectangle below?

Alik [6]

Answer:

45.5 m²

Step-by-step explanation:

Area (Shaded) = Area (Rectangle) - Area (Trapezoid)

Area (Shaded) = lb - 1/2 x (a + b) x h
Area (Shaded) = 17 × 13 - 1/2 × (10 + 17) × 13
Area (Shaded) = 13 (17 - 27/2)
Area (Shaded) = 13 × 7/2
Area (Shaded) = 91/2
Area (Shaded) = 45.5 m²

F(x) = 4x2 + 5x - 3 g(x) = 4x2 – 3x2 + 5 Find (f +g)(x).

kondaur [170]

Answer:

5x + 12

Step-by-step explanation:

simplify f(x) and g(x)

g(x) = 4*2 -3*2 +5

g(x) = 8 -6 + 5

g(x) = 7

and

f(x) = 4*2 + 5x -3

f(x) = 8 + 5x - 3

f(x) = 5x + 5

So (f + g)(x) = f(x) + g(x)

(f + g)(x) = (5x + 5) + (7)

(f + g)(x) = 5x + 12

Select the correct answer from each drop-down menu.

romanna [79]

Answer:

Area of ΔXYZ = n(r * r) square units

Step-by-step explanation:

Sides of ΔABC are 30 units, 40 units and 60 units.

Corresponding sides of another triangle XYZ are r times as long as the sides of ΔABC.

Therefore, sides of ΔXYZ will be, 30r units, 40r units and 60r units.

Perimeter of the triangle XYZ = 30r + 40r + 60r

= 130r units

If the area of ΔABC = n square units

Then the ratio of the area of ΔXYZ and ΔABC = (Ratio of the sides of ΔXYZ and ΔABC)²

$\frac{\text{Area of triangle XYZ}}{\text{Area of triangle ABC}}=(\frac{\text{Side length of XYZ}}{\text{Side length of triangle ABC}})^2$

$\frac{\text{Area of triangle XYZ}}{n}=(r)^2$

Area of ΔXYZ = nr² ≈ n(r * r)

Therefore, Option (3) will be the answer.
