Each crayon weighs 9 grams. First, if the box is 15 grams, you need subtract 105 with 15, which is 90. Then, divide 90 by 10(the amount of crayons), and you get 9, so each crayon weighs 9 grams
Answer:
5x³ + 5x² - 55x - 15
Step-by-step explanation:
simplify the expression:
5(x − 3)(x² + 4x + 1)
use the distributive property to multiply 5 by x-3
(5x - 15) (x² + 4x + 1)
Use the distributive property to multiply 5x−15 by x²
+4x+1 and combine like terms
5x³ + 5x² - 55x - 15

Answer:
Number of vertices are <em>34</em>.
Step-by-step explanation:
The relation between the number of vertices, number of edges and number of faces was given by <em>Euler's formula</em>, which is as under:
Where is the number of faces in the polyhedron.
is the number of vertices in the polyhedron and
is the number of edges in the polyhedron.
Let us try to apply this formula in a cube. We know that number of vertices are 8, number of edges are 12 and number of faces are 6.
6 + 8 - 12
Hence, the formula is applicable.
Applying Euler's formula in the given question.
F = 14
E = 46
V = ?
Using Euler's Formula:
Hence, number of vertices are <em>34</em>.
