Answer:
7/8
Step-by-step explanation:
The numbers that are not 3 are 1, 2, 4, 5, 6, 7, and 8.
7 out of 8 numbers.
P(not 3) = 7/8
C, the question asks for a fraction of shapes that 're either triangles or pentagons. Meaning all triangles and pentagons.there is 2 triangles and 5 pentagons. So in total there is 7 shapes. Overall there is 12 shapes. So the fraction will be 7/12. OR you could add the fractions 1/6 and 5/12. You would need to find a common denominator, which is 12. So multiply both parts if 1/6 by 2. It will make 2/12. And add 2/12 and 5/12. 2/12+5/12=7/12. The answer is C.
The sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11
<h3>Sum of expressions</h3>
Expressions are equations separated by mathematical signs. This expressions are known to contains certain unknowns
Given the following expression
10x^2 +7x+6 and 6x + 5
We are to take the sum of both expression to have:
f(x) = 10x^2 +7x+6 + 6x + 5
Collect the like terms
f(x) = 10x^2 + 7x + 6x + 6 + 5
f(x) = 10x^2 + 13x + 11
Hence the sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11
