If 3x-y=123x−x=123, x, minus, y, equals, 12, what is the value of \frac{8^x}{2^y} 2 y 8 x start fraction, 8, start superscript

nlexa [21]

Answer:

$\frac{8^x}{2^y}$ = 4096

Step-by-step explanation:

Rules:

$\frac{a^m}{a^n}=a^{m-n}$
$a^m\times a^n= a^{m+n}$
$(a^m)^n=a^{m\times n}$

Given that,

3x-y =12

Therefore

$\frac{8^x}{2^y}$

$=\frac{(2^3)^x}{2^y}$ [ since $8=2^3$ ]

$=\frac{2^{3x}}{2^y}$ [ applying 3rd rule]

$=2^{3x-y}$ [ applying 2nd rule]

$=2^{12}$ [ since 3x-y =12]

=4096

The length of three sides of a triangle are 12, 35 and 37 centimeters. Determine whether the triangle is a right triangle. Show

Aleks04 [339]

Answer:

it is a right triangle

Step-by-step explanation:

confirm if it is a right triangle using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

12² + 35²

144 + 1225 = 1369

square toot of 1369 is 37

12² + 35² = 37²
