He is correct
basically you have
h times base1+h times bsae 2 all divided by 2
that equals
(hb1+hb2)/2
if we undistribute h using distributive property which is ab+ac=a(b+c)
(h)(b1+b2)/2

if you split the trapezoid in half with a horizontal line that passes through the halfway point of the height and take those two shapes and put them side by side and cut the triangles off the ends and add them, you will see why this is true

the reason is becuase you can get to the area formula from that is height times (b1+b2)/2

2 trains leave the station at the same time. Train A is traveling 16 miles slower than train B. The two trains are 720 miles apa
Ber [7]

Answer: the rate of speed for train A is 66 miles per hour.

Step-by-step explanation:

Let x represent the speed of train B.

2 trains leave the station at the same time. Train A is traveling 16 miles per hour slower than train B. This means that the speed of train A would be x - 16 miles per hour.

The two trains are 720 miles apart after 4 hours. It means that both trains traveled a total distance of 720 miles in 4 hours.

Distance = speed × time

Distance travelled by train A after 4 hours is

4(x - 16) = 4x - 64

Distance travelled by train B after 4 hours is

4 × x = 4x

Since the total distance travelled by both trains is 720 miles, then

4x - 64 + 4x = 720

8x = 720 - 64 = 656

x = 656/8 = 82 miles per hour

The speed of train A would be

82 - 16 = 66 miles per hour.

A weed called the raindrop vine is known for growing at a very fast rate. It can grow up to 0.75 feet per day. How fast in inche
jarptica [38.1K]

1 foot = 12 inches.

0.75 feet x 12 inches per foot = 9 inches per day.

1 day = 24 hours.

9 inches /  24 hours = 0.375 inches per hour ( 3/8 inch per hour)

Not sure if you need a decimal or fraction for an answer so I provided both.

What property is illustrated by the statement? 0 + x = x A. Inverse Property of Multiplication B. Commutative Property of Additi
Firlakuza [10]
<h2>Answer:</h2>

Option: D is the correct answer.

The property which is illustrated by the given statement is:

              D. Identity Property of Addition

<h2>Step-by-step explanation:</h2>

We know that an identity is a value which when added to any element of the set gives the resultant as the element itself.

Also, we know that the identity under addition is always: zero.

Because when zero is added to any number then the resultant is the number itself i.e. adding zero does not affect the value.

Hence, by the Identity Property of Addition we have:

                              0 + x = x
