Answer:

Step-by-step explanation:

18's factors are 2 * 3 * 3

The two 3s can reduce the result further. sqrt (2 * 3 * 3)

square root 18 = 3*sqrt(2)

There are two sides with this length. Their total is 3sqrt(2) + 3sqrt(2) = 6√2

The perimeter is the sum of all three sides = 6 + 6√2

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 area of a rectangle is 265.5 m2. If the length is 18 m, what is the perimeter of the rectangle?

julia-pushkina [17]

Answer:

65.5 m

Step-by-step explanation:

Step 1. Find the width of the rectangle.

The formula for the area of a rectangle is

A = lw

Data:

A = 265.5 m²

l = 18 m

Calculation:

265.5 = 18w

w = 265.5/18 = 14.75 m

Step 2. Calculate the perimeter

The perimeter (P) of a rectangle is the sum of the lengths of its sides.

P = 2(l + w) = 2(18 + 14.75) = 2 × 32.75 = 65.5 m

The perimeter of the rectangle is 65.5 m.
