so area are mutiplied by 2²=4
Area B=816*4=3264 (cm²)

What is the answer for 1/4 ( 12x + 24 ) -9x

Gekata [30.6K]

The final expression is $-6x+6$

Step-by-step explanation:

The expression that we have is

$\frac{1}{4}(12x+24)-9x$

In order to solve the expression, we start by applying the distributive property to the bracket. We get:

$\frac{1}{4}\cdot 12x + \frac{1}{4}24 -9x$

Simplifying,

$3x+6-9x$

Now we add the two terms in x, and we find:

$(3x-9x)+6=\\-6x+6$

Which is the final expression.

Pedro’s car odometer measures the distance driven in kilometers. Pedro determines that, for every 810 kilometer he drives, he dr

Troyanec [42]

Answer:

The ratio of a unit rate of kilometers to miles of the distance measured by the odometer is 1 km : 0.63 miles.

Step-by-step explanation:

Given;

distance measured by odometer in kilometer, = 810 km

distance measured by odometer in miles, = 510 miles

The ratio of a unit rate of kilometers to miles of the distance measured by the odometer is calculated as;

$d = \frac{810 \ km}{510 \ miles} \\\\d = \frac{810 \ km \ \times \ \frac{1}{810 \ km} }{510 \ miles \ \times \frac{1}{810 \ km} } \\\\d = \frac{1 \ km}{\frac{510}{810} \ miles } \\\\d = \frac{1 \ km}{\frac{17}{27} \ miles} \\\\d = 1 \ km : \frac{17}{27} \ miles\\\\d = 1 \ km : 0.63 \ miles$

Therefore, the ratio of a unit rate of kilometers to miles of the distance measured by the odometer is 1 km : 0.63 miles.
