Find the product: 5(2x2 + 4x + 3)

10x^2+20x+15

Step-by-step explanation:

5(2x^2+4x+3)

u distributed it and u get

10x^2+20x+15

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:

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
