Answer:

x = 20.1

Step-by-step explanation:

First up you need to multipy the numbers on the outside with the ones on the inside

This would mean that

0.4(2x + 0.3) = 1/3(6x  - 7.2) will change to

0.8x + 0.12 = 2x - 2.4

You just have to solve for x now:

2.4 + 0.12 = 2x - 0.8x

2.52 = 1.2x

x = 2.1

The value of c is equal to _____.
DENIUS [597]

For this case we have that by definition, the Pythagorean theorem states that:

c = \sqrt {a ^ 2 + b ^ 2}

Where:

a, b: Are the legs

c: It is the hypotenuse

According to the figure we have to:

a = 20\\b = 21

Substituting in the formula we have:

c = \sqrt {(20) ^ 2 + (21) ^ 2}\\c = \sqrt {400 + 441}\\c = \sqrt {841}\\c = 29

Answer:

Option D
