Answer:
√55 ≈ 7.4
Step-by-step explanation:
The easiest way to find the square root of 55 is to use a calculator.
√55 ≈ 7.4161984871
Rounded to the nearest tenth, this is ...
√55 ≈ 7.4
__
You can make a first approximation of the root by linearly interpolating between the roots of the perfect squares* on either side of 55.
√49 = 7
√64 = 8
√55 ≈ 7 +(55 -49)/(64 -49) = 7 6/15 = 7 2/5
√55 ≈ 7.4
_____
* For numbers greater than 3.3, this sort of approximation will give the value of the root accurate to the nearest tenth. The approximation is better for larger numbers.
Step-by-step explanation:
3³⁸ - 3³⁷
= 3³⁷(3 - 1)
= 2 * 3³⁷
= 2 / [3^(-37)].
Hence x = -37.

Answer:
if its all one equation x = -y - 22
Step-by-step explanation:
2y + 4 + 10+ 2x + 10 + 18
2x + 2y + 44
2x = -2y - 44
x = -y - 22
