Answer:
128.605 m²
Step-by-step explanation:
Find the areas of the top triangle, and the bottom triangle and add them together.
The top triangle consists of 2 smaller triangles. Look at the larger one, the height is 4.93 and the base is 17. The area is...
A = (1/2)(17)(4.93)
A = 41.905 m²
The bottom triangle consists of 2 smaller triangles. Look at the larger one, the height is 10.2 and the base is 17. The area is...
A = (1/2)(17)(10.2)
A = 86.7 m²
The total area is 41.905 m² + 86.7 m² = 128.605 m²
Answer:
Step-by-step explanation:
hello :
you add 11² to complete the square
x²+22x+11²=50+11²
(x+11)² = 171
Answer:
Step-by-step explanation:
f(x)=5x+7
g(x)=-2x-4
g(f(x))=g(5x+7)=-2(5x+7)-4=-10x-14-4=-10x-18
=-10x+(-18)
