Simplify each expression by combining like terms.

Answer:
9. 2a+5 ; 11. 2x+11y+4 ; 13. -a+3b-1 ; 15. (10c^2)-2c+5 ; 17. (5(a^2)(b^2))-(a(b^2))
Step-by-step explanation:
You should group each term with the same variables and then simplify
9. 9a + 8 - 2a - 3 - 5a
=(9a-2a-5a)+(8-3)
= 2a + 5
11. 7x + 2y + 5 - 5x + 9y - 1
= (7x-5x)+(2y+9y)+(5-1)
=2x+11y+4
13. -6+3a-b-4a+4b+5
=(3a-4a)+(-b+4b)+(-6+5)
=-a+3b-1
15. 8c^2 -c+3+2c^2 -c +2
=(8c^2 + 2c^2)+(-c-c)+(3+2)
=(10c^2)-2c+5
17. 6a^2b^2 + 3ab^2 -a^2b^2 -4ab^2
=(6a^2b^2 -a^2b^2)+(3ab^2 -4ab^2)
=(5(a^2)(b^2))-(a(b^2))

so we can do 2 86/100 and then we simplify 2 43/50 is dividing the numerator and the denominator in half and that is the simplest form
2 43/50
Final answer:
The decimal number 2.86 cannot be converted to a mixed number because it doesn't contain a whole part and a fraction part. Therefore, it remains as 2.86.
Explanation:
The question asks to express 2.86 as a mixed number in simplest form. Since 2.86 is a decimal and not a fraction, it's already in its simplest form and does not convert to a mixed number because it does not have a whole part and fraction part.
A mixed number example would be '3 1/2' which has a whole part (3) and a fraction part (1/2). In this case, 2.86 is a decimal more than 2 and less than 3, and it doesn't contain fractions, so it’s simply 2.86.

What is geometry?
A subfield of mathematics called geometry examines the dimensions, placements, angles, and sizes of objects. 2D Geometric shapes. flat forms. The square is a two-dimensional shape having all the sides equal to each other.
Given that the box is 10.38 in wide and the pizza is 10 ( 1/3 ) inches wide. The shape will be analyzed as below:-
Diameter of pizza = 10 ( 1 / 3 ) = 10.333 inches
The width of the box = 10.38 inches
Difference = 10.38 - 10.33 = 0.05 inches gap
Therefore, the square box showed big enough to fit the pizza inside.
