In the given figure, there are two right angled triangles.
Area of triangle = 1/2 × b × h
Area of shaded region = area of larger triangle - area of smaller triangle
= 1/2 × 15 × 18 - 1/2 × 8 × 9
= 135 - 36
= 99 ft^2
Thus, area of shaded region is 99 ft^2.
answer: y= 2x^2+2x-4
steps:
y= (2x+4)(x-1)
*FOIL method* y= (2x^2-2x+4x-4)
*simplify* y= 2x^2+2x-4
7 should be the answer.
7 doubled is 14. Hope this helps
Given:
Composite figure
To find:
The shapes in the composite figure.
Solution:
The image splitted into three shapes.
- Draw a line from top vertex to bottom vertex.
- We get one triangle.
- Similarly, draw another line adjacent to the previous line.
- We get another triangle and rectangle.
Therefore a composite figure divided into a rectangle and two triangles.
Answer:
2:00 PM
Step-by-step explanation:
I figured out that the car is going 40 mph seeing as how it went 20 miles in 30 minutes.
I used this and found out how many hours it would take to get to 200 miles at this rate:
200/40 = 5
I divided 40 by 200 as 200 is the end goal and the car is going 40 mph.
The 5 is 5 hours, so I added 9 and 5 to get 14 which is 2:00 PM
Hope this helps!! :)
