Area=\frac{(base)(height)}{2}

2. Now, substitute the values given in the problelm above into the equation:

Area=\frac{(6units)(7units)}{2} \\ Area=21units^{2}

Therefore, as you can see, the answer is: 21units^{2}

Simplify. (5x4 + 3)2 A. 25x8 + 30x4 + 9 B. 10x8 + 30x4 + 6 C. 25x16 + 30x4 + 9 D. 25x8 + 9​
elixir [45]

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

( 5x⁴ + 3)²

( 5x⁴ + 3)(5x⁴ + 3)

<u>Expand</u><u> </u><u>using</u><u> </u><u>FOIL</u>

That's

(5x⁴)(5x⁴) + 5x⁴(3) + 3(5x⁴) + 3(3)

We have

<h3>25 {x}^{8}  +  {15x}^{4}  +  {15x}^{4}  + 9</h3>

<u>Add and simplify like terms</u>

We have the final answer as

<h2>{25x}^{8}  +  {30x}^{4}  + 9</h2>

Hope this helps you

What does the constant term in the polynomial 4x2 + 9 represent?
shusha [124]

Answer:

The constant in the polynomial is 9. A constant number is a number that does not change during the equation. This equation is 4x² + 9. Since you are just adding 9 the number of 9 does not change. If you were multiplying 9 it would not be a constant anymore because it does not stay the same throughout the equation.

Hope This Helps :)
