Answer:
175.1
Step-by-step explanation:
Find the area of the semicircle:
(pi • radius²) / 2. [Radius is half of diameter]
(3.14 • 4²) / 2
(3.14 • 16) / 2
(50.24) / 2
25.12
Find the area of the parallelogram:
(base • height)
(30 • 5)
150
Add the areas of both shapes to get total area
25.12 + 150 = 175.12, round to the nearest tenths, 175.1
Hope this helps!
The question is an illustration of selection (or combination)

The answer to your question is: letter C
Step-by-step explanation:
4x² + 5x - 6
Process
4 x - 6 = - 24
Find two numbers that added gives + 5 and multiply gives -24
These numbers are + 8 and - 3
4x² + 8x - 3x - 6
4x ( x + 2) - 3(x + 2)
(x + 2) (4x - 3)
