Answer: Ravi would drive 250 miles for both plans to cost the same.
Step-by-step explanation:
Let x represent the number of miles for which Ravi needs to drive for the two plans to cost the same.
The first plan has an initial fee of $59.96 and costs an additional $0.14 per mile driven. It means that the cost of driving x miles with this plan is
0.14x + 59.96
The second plan has an initial fee of $69.96 and costs an additional $0.10 per mile driven. It means that the cost of driving x miles with this plan is
0.1x + 69.96
For both plans tho be the same, the number of miles would be
0.14x + 59.96 = 0.1x + 69.96
0.14x - 0.1x = 69.69 - 59.69
0.04x = 10
x = 10/0.04
x = 250

740 square meters
Just find the areas of all the faces of the prism. And add then all up:
Area of rectangular base (bottom):
16 • 10= 160 square meters
Area of triangle facing front:
1/2 • 15 • 16= 120
Multiply 120 by 2 cause theres a same triangle facing back the prism: 120 • 2= 240
Area of rectangle facing right:
10 • 17= 170
Multiply 170 by 2 cause theres a same rectangle facing left the prism: 170 • 2= 340
Add them all up together:
160+ 240+340= 740
Comm.ent me if u have any questions
MARK ME BRAINLIEST TYSM! Say if my answer was wrong/right!
The error is in the first step. It should be (+8 plus or minus the square root of the quantity eight squared minus four times one times seven ). This is because "b" is -8 so -b is -(-8) = +8
