Solve the equation:
(p + 3)(1 - p)

p²-2p+3

Step-by-step explanation:

(p + 3)(1 - p)

p-p²+3-3p

=p²-2p+3

Hope this helps :)

5x+2x=49

7x=49

x=7. 35 apples

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:
