An expression is shown. 2(3/5x+3) - (2/3x-1) create an equivalent expression without parenthesis

6/5x -2/3x + 4

Step-by-step explanation:

Simplify the equation

6/5x + 3 -2/3x + 1

6/5x -2/3x + 4

not simplified all the way, but is just exquivalent

Answer 1 13/15x + 5 if simplified or 28/15x + 5 non-simplified

Step-by-step explanation:

2(3/5x+3) = 6/5x + 6 (also can simplfy to 1 1/5x +6)

6/5x + 2/3 = 18/15 + 10/15 = 28/15x ( also can to 1 13/15x)

6-1=5

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
