Answer:
85
Step-by-step explanation:
1/2(6x5) = 15
15x4 = 60
5x5= 25
25 + 60 = 85
So the equation for a trapezoid is

, with the b variable being the 2 bases, h variable for height, and the a variable for area. Firstly, we will need to plug in the appropriate numbers into the equation, and it'll look like this:

Next, we will need to combine 12 and 14, then divide the sum by 2. Your equation should look like this:

Lastly, just divide each side by 13, and your answer should be
Answer:0 and -20
Step-by-step explanation:
5x=0;
x=0/5.
3x+60=0;
3x= -60;
x= -60/3;
x= -20
Answer:
15 miles
Step-by-step explanation:
the 2 mph is a red herring. If there is a rate of 10 mph, and the trip took 1.5 hours, the 1 hour=10 miles, and the .5=5 miles, add em up and its 15 miles
