An equation is formed of two equal expressions. The missing pieces of the solution of the quadratic equation are 50, 3, and -8.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

To fill the missing piece of the solution of the quadratic equation, you need to balance each of the equations. Therefore, the solution to the problem can be written as,

-32 = 2(x^2 + 10x)\\\\-32 + 50 = 2(x^2 + 10x + 25)\\\\18 = 2(x + 5)^2\\\\9 = (x + 5)2\\\\\pm 3= x + 5\\\\x = -2\ \ {\rm or}\ \ x = -8

Thus, the solution of the quadratic equation is -2 or -8.

Hence, the missing pieces of the solution of the quadratic equation are 50, 3, and -8.

The sum of two numbers is 21 the second number is 6 times the first number of
romanna [79]

the numbers are 3 and 18

let the first number be n then the second number = 6n and the sum

sum = n + 6n = 21 thus

7n = 21

divide both sides of the equation by 7

n = \frac{21}{7} = 3

the numbers are 3 and 6 × 3 = 18 → (3 + 18 = 21)

6.5. Does Spending Measure Welfare? Suppose a community spends $1 million on salaries and equipment for its police department. B
marta [7]

Answer:

(a) Measured GDP will decrease by $200,0000

(b) No

Step-by-step explanation:

(a) Gross Domestic Product (GDP) is the total value in monetary terms of al the goods produced in a geographic location.

There will be a $200,000 decrease in the value of the GDP of the community as a result of reduction in the community spending from $1 million to $800,000.

(b) Generally, GDP is not a true indicator of welfare, likewise in this case, GDP does not reflect the welfare of the community.

There's a decrease in the community spending from $1 million to $800,000 but there's an increase in the welfare of the community as a result of decrease in crime rate.

A square has a side length of 4a. One dimension is decreased by 5 and the other dimension is decreased by 5. Expand and simplify
kondaur [170]

Answer:

Area= 16a^2-40a+25

Step-by-step explanation:

given that the side of the square is 4a

The expression for the area can be solved by

1. subtracting 5 from the sides of the square i.e (4a-5)

2. Solving for the area of the square using

Area= l^2

Area= (4a-5)^2\\Area= (4a-5)(4a-5)\\

opening the bracket and expending we have

Area= 16a^2-20a-20a+25\\Area= 16a^2-40a+25

the expression is Area= 16a^2-40a+25
