Answer:
Step-by-step explanation:
(5x^3+4x^2)−(6x^2−2x−9)
To find the opposite of 6x^2−2x−9 find the opposite of each term.
5x^3+4x^2−6x^2+2x+9
Combine 4x^2 and 6x^2 to get −2x^2.
5x^3-2x^2+2x+9
The answer to your question is D , it is 2/3 simple math even easier if you use a calcul
Answer:
<h2>y = 4</h2>
Step-by-step explanation:
Put x = 9 to the equation 3x + 4y = 43
(3)(9) + 4y = 43
27 + 4y = 43 <em>subtract 27 from both sides</em>
4y = 16 <em>divide both sides by 4</em>
y = 4
If a polygon has 5 sides, then it is a regular pentagon
False: regular pentagon = equiangular. There are pentagons that have 5 sides that are not equiangular
5/2 * 6 = 15
h/6 * 6 = h
so
h = 15
