Answer:
8.1192
you need to multiply the decimal to the grand number:
0.08 x 101.49 = 8.1192
The formula is 1/2 x ( a + b ) x h
A and b are the top and bottom sides and h is always the perpendicular height.
Now replace the variables...
1/2 x (6 + 14 ) x 8.4
And then...
1/2 x 20 x 8.4 which will give you 84cm^2
Hope this helps! Anymore questions let me know :)

Answer:
A. x < 3
B. X > 9
c. x < 1
d. x < -2
Step-by-step explanation:
For A. 2x+1 < 7
First, subtract 1 from both sides
Then, we will get
2x+1 -1 < 7 - 1
2x < 6
Now, divide both sides by 2
2x / 2 < 6/2
x < 3
For B. X-5 >4
Add 5 to both sides,
Then, we will get
X -5 +5 > 4 + 5
X > 9
For c. 2x+3 <5
Subtract 3 from both sides
2x +3 -3 < 5 - 3
2x < 2
Divide both sides by 2
2x / 2 < 2/2
x < 1
For d. 2x-3 x >2
First, evaluate 2x -3x
2x -3x = -x
Then, 2x-3 x >2 becomes
-x > 2
Now, divide both sides by -1
-x/-1 > 2/-1
x < -2
(NOTE: The sign changes when you divide or multiply by a negative sign)
