is each expression equilvant to 2x^2-50 a.) 2(x-5)(x+5) b.) -2(x+5)(x+5) c.) -2(5-x)(x+5)

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

it would more likely be bald eagle because its has more in the box so about 75%.

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:
