Answer:
d. no; 0.7+1.4=2.1 is the answer...
because for forming a triangle the sum of two sides should be greater than the third side always.
while in this case it is equal so it is not possible to form a triangle...
Area of Trapezoid is = 1/2 x height x (base1 + base2)
Here, Area = 98, base1 = 8, base2 = 20 and height = unknown (x)
So, 1/2 x height x (8+20) = 98
==> 1/2 x height x 28 = 98
==> height x 14 = 98
==> height = 98/14
==> height = 7 units
So, the final answer is --> the value of x = 7 units
6.4 Miles
30/4=7.5 (how many minutes it takes Kevin to run a mile)
48/7.5=6.4 (how many miles he can run at a 7.5 mile pace)
