Answer/Step-by-step explanation:
1. The figure is composed of a triangle and a rectangle.
Area of the triangle = ½*base*height
base = 4 ft
height = 12 - 8 = 4ft
Area of triangle = ½*4*4 = 8 ft²
Area of rectangle = length * width
Length = 8 ft
Width = 4 ft
Area of rectangle = 8*4 = 32 ft²
✔️Area of the figure = 8 + 32 = 40 ft²
2. The figure is composed of a semicircle and a triangle
Area of the semicircle = ½(πr²)
radius (r) = 3 cm
π = 3
Area = ½(3*3²) = 13.5 cm²
Area of triangle = ½*base*height
base = 3*2 = 6 cm
height = 6 cm
Area = ½*6*6 = 6 cm²
✔️Area of the figure = 13.5 + 6 = 19.5 cm²
90°+b+b =180
90°+ 2b=180
2b=180-90
2b= 90
<u>2</u><u>b</u><u>=</u><u>9</u><u>0</u>
<u>2</u> = 2
b=45°
ave tried I don't know if its correct
We can’t measure these. How long is each of them

Step-by-step explanation:
Hi :)
x = 1/2n
Subtract 17nx from both sides
9−nx−17nx = 0
Combine −nx and −17nx to get −18nx
9 −18nx = 0
Subtract 9 from both sides
−18nx = −9
The equation is in standard form
(−18n)x=−9
Divide both sides by −18n
(-18n)x/ -18n = -9/ -18n
Dividing by −18n undoes the multiplication by −18n
x= -9/ -18n
Divide −9 by −18n
x= 1/2n
Hope this helps :)
