Hey smart cookie ;)
So with this all we need to do is factor the expression.
Our answer is going to be 2x(16x^4+15)
Let me know if you have other questions!
Have a terrific day.

The answer would be $22.68!
If Andy bought 3 paintbrushes for $1.75 each, then we just multiply how much they cost by the number that the bought.
1.75 x 3 = 5.25
If Andy bought 7 tubes of oil paint, we just do the same thing we did in the first step! Multiply how much they cost by the number that the bought.
2.49 x 7 = <span>17.43</span>
<h3>Given</h3>
1) Trapezoid BEAR with bases 11.5 and 6.5 and height 8.5, all in cm.
2) Regular pentagon PENTA with side lengths 9 m
<h3>Find</h3>
The area of each figure, rounded to the nearest integer
<h3>Solution</h3>
1) The area of a trapezoid is given by
... A = (1/2)(b1 +b2)h
... A = (1/2)(11.5 +6.5)·(8.5) = 76.5 ≈ 77
The area of BEAR is about 77 cm².
2) The conventional formula for the area of a regular polygon makes use of its perimeter and the length of the apothem. For an n-sided polygon with side length s, the perimeter is p = n·s. The length of the apothem is found using trigonometry to be a = (s/2)/tan(180°/n). Then the area is ...
... A = (1/2)ap
... A = (1/2)(s/(2tan(180°/n)))(ns)
... A = (n/4)s²/tan(180°/n)
We have a polygon with s=9 and n=5, so its area is
... A = (5/4)·9²/tan(36°) ≈ 139.36
The area of PENTA is about 139 m².
Answer:
b. the degree is 3
Step-by-step explanation:
degree is the highest exponent
Subtract the y values to one side then the numbers to the other so as x values to one side then the numbers to the other
