For what value of x must the quadrilateral be a parallelogram x +5 equals 2x -5

x=10

Step-by-step explanation:

x+5=2x-5

x=2x-10

-x=-10

x=10

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

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:
