In parallelogram abcd, ab=18. identify ad.

cannot be determined

Step-by-step explanation:

In a parallelogram, the two opposite sides are equal. From the parallelogram ABCD given, it can be inferred that AB is parallel to CD and AD is parallel to BC i.e AB//CD and AD//BC.

Given AB = 18, side AD cannot be determined from the figure due to incomplete data given.

The data given can only be used to determine side CD since AB is equal to CD.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
