an art class is making a mural for their school which has a triangle drawn in the middle the length of the bottom of the triangle is X another side is 7 more than four times the length of the bottom of the triangle the last side is 5 more than the bottom of the triangle write and simplify an expression for the perimeter of the triangle

im not sure

step-by-step explanation:

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

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:

b
