Answer:

Step-by-step explanation:

Part C

A = a² + 4(½ab) + b²

A = a² + 2ab + b²

Part D

A = c² + 4(½ab)

A = c² + 2ab

Part E

a² + 2ab + b² = A = c² + 2ab

a² + 2ab + b² = c² + 2ab

Part F

2ab is common

a² + b² = c²

Part G

why gosh, that's the Pythagorean theorem equation

Answer:

Part C

A = a² + 4(½ab) + b²

A = a² + 2ab + b²

Part D

A = c² + 4(½ab)

A = c² + 2ab

Part E

a² + 2ab + b² = A = c² + 2ab

a² + 2ab + b² = c² + 2ab

Part F

2ab is common

a² + b² = c²

Part G

This equation shows the explanation cancels out and in terms on both sides.

ollegr [7]

Answer:

The number of messages that will cost same both plans is <u>1000</u>.

Step-by-step explanation:

Given,

For 1st offer:

Total number of messages = 500

Charge of each message after 500 messages = $0.10

For 2nd offer:

Total number of messages = 400

Charge of each message after 400 messages = $0.20

We need to find out the number of messages can be sent for equal cost of both plans.

Solution,

Let the number of messages be 'm'.

So For 1st offer:

Total cost 'c' is equal to fixed cost for 500 messages plus charge of each message multiplied with number of messages.

framing in equation form, we get;

c=500+0.10m

Again for 2nd offer:

Total cost 'c' is equal to fixed cost for 400 messages plus charge of each message multiplied with number of messages.

framing in equation form, we get;

c=400+0.20m

Now the question said that the charge would be the same.

So we can say that;

500+0.10m=400+0.20m

On combining the like terms, we get;

500-400=0.20m-0.10m\\\\100=0.1m\\\\

Now using multiplication property, we will multiply both side by '10' and get;

100\times 10=0.1m\times10\\\\1000=m

Hence The number of messages that will cost same both plans is <u>1000</u>.
