Find the area of the rectangle polynomial

Answers

Answer 1

Answer:

Answer:

$\Longrightarrow: \boxed{\sf{8x^2+12x-8}}$

Step-by-step explanation:

Using the distributive property, you multiply by the area to find the area of the rectangle polynomial.

$: \Longrightarrow \sf{(Area)= (2x+4)*(4x-2)}$

Solve.

(2x+4)*(4x-2)

Multiply by expand.

Use the distributive property.

Distributive property:

⇒ A(B+C)=AB+AC

Use the FOIL method.

FOIL method:

$\Longrightarrow: \sf{\left(A+B\right)\left(C+D\right)=AC+AD+BC+BD}$

$\Longrightarrow: \sf{2x\cdot \:4x+2x\left(-2\right)+4\cdot \:4x+4\left(-2\right)}$

$\Longrightarrow: \boxed{\sf{=8x^2+12x-8}}$

Therefore, the correct answer is 8x²+12x-8.

I hope this helps! Let me know if you have any questions.

Answer 2

Answer:

hello,

$Area =(2x + 4) * ( 4x - 2) \n Area =8 {x}^(2) - 4x + 16x - 8 \n Area = {8x}^(2) + 12x - 8$

$\boxed{crsjr}$

A boat is marked up 20% on the original price. The original price was $50. What is the sale price of the boat before sales tax?

Answers

The price of the boat before sales tax is $60.

What is the percentage?

The percentage is a ratio that can be expressed as a fraction of 100.

Gien that, the boat is marked up 20% of the original price of $50.

Therefore, the price of the boat is:

50 + 20% of 50

= 50 + 20×50/100

= 50 + 10

= 60

Hence, the price of the boat before sales tax is $60.

A ballon is released from the top of a platform that is 50 meters tall

Answers

Your question is not clear, mainly because you didn't ask one. But it probably has
something to do with the subsequent motion of the balloon after it's released.

That's going to depend on ...

-- the material of which the balloon is made, especially its weight,
-- the substance with which the balloon is filled, especially its density,
-- the size of the balloon, especially its volume,
-- the temperature, pressure, humidity, and density of the air around the balloon,
-- the wind speed and direction in the neighborhood of the balloon,
-- whether the balloon is pushed, or simply let go of,
-- if pushed, then the direction and speed of the push.

Without any of this information, no answer to a question could be given,
even if there were a question.
