Simplify 3 radical sign 128-2 radical sign 6•4 radical sign 3. Show all work. Please help me it’s due today!!!

alexdok [17]

Answer:

Step-by-step explanation:

3*sqrt(128) - 2sqrt(6)*4sqrt(3)

3*sqrt(128) = 3*sqrt(64*2) But the square root of 64 = 8

3sqrt(128) = 3*8 * sqrt(2) = 24 sqrt(2)

==================

2* sqr(6)*4sqrt(3) Combine the 2 and 4 = 8. Break apart the 6.

8* sqrt(3*2)*sqrt(3) Break apart the sqrt(3*2)

8*sqrt(3*2)*sqrt(3) = 8 * sqrt(3)*sqrt(2)*sqrt(3) but sqrt(3)*sqrt(3) = 3

8*sqrt(3)*sqrt(2)*sqrt(3) = 8*3*sqrt(2) = 24sqrt(2)

===================

24sqrt(2) - 24*sqrt(2)

The expression that is most useful for finding the year where the population was at a minimum would be 8(x − 9)² + 216.

Given expression 8x² − 144x + 864 is used to approximate a small town's population in thousands from 1998 to 2018, where x represents the number of years since 1998.

<h3>What is a quadratic equation?</h3>

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given expression is 8x² − 144x + 864

Let y = 8x² − 144x + 864

also, y - 864 = 8x² - 144x

by Extracting common factor 8 on the right side

y - 864 = 8(x² - 18x)

Add (18/2)² on both sides, we get

y - 864 + 8(18/2)² = 8 (x² - 18x + 81²)

y - 864 + 648 = 8 (x² - 8x + 9)

on simplification

y - 216 = 8 (x - 9)²

y = 8(x - 9)² + 216

therefore, y = 8 (x - 9)² + 216
