Can a quadratic function ever be an odd function? Explain why.

The two different ways of addition are mentioned above.

Given that,
To estimate 368+231 two different ways.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
One way,
= 368 + 231
= 400 - 32 + 200 + 31
= 600 - 1
= 599

Second way
= 368 + 231
= 300 + 68 + 200 + 31
= 500 + 99
= 599

Thus, the two different ways of addition are mentioned above.

we know that

One very simple form of estimation is rounding.

To round off whole numbers:

Find the place value you want (the "rounding digit") and look to the digit just to the right of it.

If that digit is less than , do not change the "rounding digit" but change all digits to the right of the "rounding digit" to zero.

If that digit is greater than or equal to , add one to the rounding digit and change all digits to the right of the rounding digit to zero.

Part a) Estimate rounding the numbers to nearest hundreds

------> round up to

------> round down to

so

therefore

the answer part a) is

Part b) Estimate rounding the numbers to nearest tens

------> round up to

------> round down to

so

therefore

the answer part b) is

Answer:

12

Step-by-step explanation:

Answer:

15 times as much as 1 fifth of 12 is  36

Step-by-step explanation:

Given the statement: 15 times as much as 1 fifth of 12

or we can write this as:

15 times as much as 1/5 of 12

''of '' means multiply

"1/5 of 12" means  

"times" means

then;

⇒

⇒

Therefore,  15 times as much as 1 fifth of 12 is 36

• 15 x (¹/₅ x 12)
• The result is 36

Further explanation

The Problem:  

• 15 times as much as 1 fifth of 12.
• Write an expression to match, and then evaluate.

The Process:

Here are some early expressions that need attention.

• 1 fifth is
• 1 fifth of 12 is

Let us write an expression to match for 15 times as much as 1 fifth of 12.

And now we evaluate the expression.

We cross out 15 and 5 because they both can be divided.

Thus, the result is 36.

Answer:

4x^2 -16

Step-by-step explanation:

(2x + 4)(2x - 4)

FOIL

first:2x*2x = 4x^2

outer: -4 *2x = -8x

inner:  4*2x = 8x

last: -4*4 = -16

Add them together

4x^2 -8x+8x =-16

4x^2 -16

The multiplication of the expression (2x + 4)(2x - 4) is 4x² - 16.

What is the simplified form of the expression?

Given the expression in the question:
(2x + 4)(2x - 4)

We can multiply the expression (2x + 4)(2x - 4) using the distributive property and the FOIL method.

(2x + 4)(2x - 4)

Apply the FOIL method:

2x( 2x - 4 ) + 4( 2x - 4 )

Apply distributive property:

2x × 2x + 2x × - 4 + 4 × 2x 4 × - 4

Multiply the terms:

4x² - 8x + 8x - 16

Collect and add like terms:

4x² - 16

Therefore, the simplified form is 4x² - 16.
