two jets leave an airport at the same time in opposite directions. the first jet is traveling at 323 mph and the other at 347 mp
skelet666 [1.2K]

Remark

This may be a little confusing, but because they are travelling in opposite directions, the distances add when you want to get how far apart they are.

d1 + d2 = 1541

Equation

Let the time this happens = t

d1 = 323*t

d2 = 347*t

323*t + 347*t = 1541 Combine like terms on the left.

670t = 1541 Divide by 670

t = 1541/670

t = 2.3 hours pass before the distance of 1541 miles are between the two planes. You might need the answer to be 2 hours 18 minutes.

Write the polynomial in standard form. Then name the polynomial based on its degree and number of terms.
gavmur [86]
To answer the question, simplify the polynomial by adding those that has the same degree of variable,
                                   6 - 3x + (6x³ - 2x³)
                                   6 - 3x + 4x³
Rearrange the polynomial with decreasing exponent or x,
                                     4x³ - 3x + 6
This is a third-degree polynomial.
