How to distribute this problem:<br> (x-8)^2 + 16

Usimov [2.4K]

Answer:

We conclude that:

$\left(x-8\right)^2+16=x^2-16x+80$

Step-by-step explanation:

Given the equation

$\left(x-8\right)^2\:+\:16$

First, solve (x - 8)²

Apply Perfect Square formula: (a - b)² = a² - 2ab + b²

$a=x,\:\:b=8$

$\left(x-8\right)^2=x^2-2x\cdot \:\:8+8^2$

$=x^2-16x+64$

so the expression becomes

$\left(x-8\right)^2+16=x^2-16x+64+16$

$=x^2-16x+80$ Add the numbers: 64+16=80

Therefore, we conclude that:

$\left(x-8\right)^2+16=x^2-16x+80$

HELP!!!!!!!!!! PLEASE!!!!!!!WILL MARK AS BRAINLIEST

<t =33 since triangle RUT is isosceles (RU = TU)

<r + <u + <t = 180 triangle = 180

33 + <u + 33 = 180

66 + <u = 180

< u =114

<rus = < sut from the diagram

<rus + <sut = <u

x + x = 114

2x = 114

divide by 2

x = 57
