40 * 7.85 = 314
32.24 + 24.02 + 24.53 = 80.79
314 - 80.79 = 233.21

Answer: Rick can type 1350 more words than Raquel.
We will follow through these 3 steps to find the answer
1) Find the number of words Raquel can type in 135 mins.
2) Find the number of words Rick can type in 135 minus.
3) Numbers of words Rick can type - Numbers of word Raquel can type.
------------------------------------------------------------------------------------------
Find the number of words Raquel can type in 135 mins
------------------------------------------------------------------------------------------
1 minute = 63 words
x135 x135
135 minutes = 8505 words
------------------------------------------------------------------------------------------
Find the number of words Rick can type in 135 mins
------------------------------------------------------------------------------------------
1 minute = 73 words
x 135 x135
145 minutes = 9855 words
------------------------------------------------------------------------------------------
Find the difference
------------------------------------------------------------------------------------------
9855 - 8505 = 1350

Answer: Rick can type 1350 more words than Raquel.
------------------------------------------------------------------------------------------
formula :1/2 height (b1+b2)
(b1+b2)=(12+18)=30
30(6)=180
180(1/2)=90
6= height
b1=12
b2=18
find the sum of base one and base two
then multiply the the height
lastly multiply 1/2 or divide by 2
If h=0 represents the base of the model, then ...
The bridge touches the base of the model at 2 feet and 6 feet from the leftmost edge of the model.
_____
When in doubt, use your calculator to graph it.
Here, the solution is not so hard. We're looking for h(x) = 0.
Multiply by -2
(x -4)² -4 = 0
(x -4) = ±√4
x = 4 ±2 = {2, 6}
