Answer:
<h2>
49.73</h2><h2>
</h2>
Step-by-step explanation:
total area = area of rectangle - area of circle
= (13 x 6) - (π 3²)
= 78 - 28.274
= 49.73 sq. units
Answer:
4x + 10y = 36 ≡ to 2x + 5y = 18
As you can see, the the coefficients on the first one are double those in the second.
12x - 9y = -60 ≡ to -4x + 3y = 20
In this case, the terms in the first one are all the same, but multiplied by -3
And by simple elimination we can say:
-24x - 8y = 40 ≡ -6x - 2y = 10
In this case, the terms of the first equation are equal to those of the latter, but all multiplied by 4.
