Answer:

(x+1)^{2} -5

Step-by-step explanation:

-2x=x^{2} -6 \\x^{2} +2x-6\\(\frac{b}{2}) ^{2} =(\frac{2}{2}) ^{2} =1^{2} =1\\so, (x^{2} +2x+1)-6+1\\ x^{2} +2x+1=(x+1)^{2} \\-6+1=5\\(x+1)^{2} -5

Sorry it took so long

Sarah opens a small bag of chocolate candies and notices that out of 210 candies, 63 are brown. She assumes the color breakdown
mezya [45]

Answer:

1440

Step-by-step explanation:

We can solve this problem by applying the rule of three.

In fact, we know that:

- Over a package of 210 candies,

- The number of brown candies is 63

- Here we want to find what is the number of brown candies when the total number of candies contained in the package is 4800

So we can set up the following rule of three:

\frac{x}{4800}=\frac{63}{210}

where

x = number of brown candies when the total number of candies contained in the package is 4800

Solving the expression for x, we find:

x=\frac{63}{210}\cdot 4800 =1440

So, Sarah can expect to find 1440 brown candies in a package of 4800 pieces.

One number is 9 more than another number, and the sum of the two numbers is 35.
Effectus [21]
<h2><u>Answer:</u></h2>

One number = x

Other number = 9 + x

Sum of the numbers = 35

Value of the smaller number (x) = ?

9 + x + x = 35 \\ 9 + 2x = 35 \\ 2x = 35 - 9 \\ 2x = 26 \\ x =  \frac{26}{2}  \\ x = 13

<h3>➟ The value of the smaller number is <u>13</u></h3>

What type of number can be written as an a fraction a/b where a and b are Integres and b is not equal to zero?
faltersainse [42]

Answer:

Integers, Terminating Decimals, Recurring Decimals, Proper and Improper Fractions.

Step-by-step explanation:

The following subset of the real number system can be written in the form \dfrac{a}{b}, b≠0.

Integers(ℤ): These are positive and negative whole numbers. For example, 5 can be written as \dfrac{5}{1}

Terminating Decimals: These are fractions that when converted to decimal numbers have an end.

e.g. \dfrac{5}{2}=2.5

Recurring Decimals: These are fractions that when converted to decimal numbers do not have an end.

e.g. \dfrac{8}{11}=0.727272...=0.\overline{72}

Proper Fractions: These are fractions of the form \dfrac{a}{b} where a<b. An examples is \dfrac{4}{5}

Improper Fractions: These are fractions of the form \dfrac{a}{b} where a>b. An examples is \dfrac{5}{4}
