Answer:
486 mm²
Step-by-step explanation:
Formula: 6a²
a² = 9²
= 81
6(81) = 6 × 81
486
The answer is the third option:
the cost is $25 for each day
We can write this question as an equation to solve it. Using L for length and W for width we know that
L+L+W+W=perimeter
2L+2W=perimeter
We can put the value of the perimeter into this
2L+2W=156cm
Next, we have to make sure all the terms (letters) are the same so we can solve it. This means we have to rewrite either the length or width in terms of the other.
We know the width is 12cm less than the length, which is the same as saying L-12
Then we substitute this into the equation and solve L
2L+2(L-12)=156
2L+2L-24=156
4L-24=156
4L=180
L=45cm
Next we use this value to find W.
45-12=33
W=33cm
<span>The
power of the root of the power of a variable can be written as a
rational power by creating a rational exponent that is the product of
the powers divided by the root. The rational exponent should be reduced
to lowest terms. For example, the seventh power of the sixth root of the
fifth power of x will be x^(7*5/6) = x^(35/6).
hope it helps

The horizontal leg has length 6 in the dashed triangle and 2 in the solid one.
The vertical leg has length 9 in the dashed triangle and 3 in the solid one.
So, all lengths have been divided by 3, implying that the scale factor was 1/3.
