Answer:
Length: 12
Width: 2
Area: 24
Step-by-step explanation:
We first find the points of C and D to find the length.
C: (-4,-5)
D: (2,-3)
The distance is 2
.
Now for the height.
A: (2,9)
D: (2,-3)
The distance is 12.
Area: 2
×12 = 24
Answer:
-26
Step-by-step explanation:
Probably feet or meters depending on where he is. I would go with feet
The best step to do next is to add 80 to both sides of equation:
5 ( x² + 8 x ) + 80 = 14 + 80
and since 80 = 5 · 16
5 ( x² + 8 x + 16 ) = 94 Answer : B )
After that we will continue like this:
5 ( x + 4 )² = 94
( x + 4 )² = 18.8 ... etc
