Mathematics
1 answer:
Minchanka [31]2 years ago
3 0

The equation x² - 8x = 16  will equal to  (x - 4)² = 32   so option (C) will be correct.

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

An expression is a mathematical proof of the equality of two mathematical expressions.

Expressions are collections of variables, numbers, addition, subtraction, multiplication, and division.

A statement expressing the equality of two mathematical expressions is known as an equation.

Given,

x² - 8x = 16

x² - 8x - 16 = 0

Add and subtract 16 to the left-hand side

(x² - 8x +16) - 16 - 16 = 0

(x - 4)² - 32 = 0

(x - 4)² =  32

Hence the expression (x - 4)² = 32 will equal to  x² - 8x = 16 .

First we have to translate our fractions into decimals:

11.25 (11 1/4) and 1.166667 (1 2/3)

multiply:

11.25 x 1.166667 = 18.75

convert back to fraction:

18 3/4

Answer:

V candle ≈ 196.9 cm³

Step-by-step explanation:

Volume of cone = ( π·r²·h)/3

V candle = V big cone -V small cone

V candle = [ π·4²·(8+5) - π·2²·5]/3

V candle = ( π·16·13 - π·4·5)/3

V candle = (π·16·13 - π·4·5)/3

V candle = π·(208 - 20)/3

V candle = π·188/3

V candle = 196.8731396

V candle ≈ 196.9 cm³

valentina_108 [34]

Answer:

y=6 x=8.49

Step-by-step explanation:

Since angles p and r are 45deg QP and QR are the same length.

the pythagorean theorem states that a^2+b^2=c^2.

so 6^2+6^2=72

the square root of 72 is 8.49.

so x or c = 8.49
