What when multiplied is 5 but when added is -11

Answers

To get two numbers that when multiplied gives 5, and when added gives -11, the calculations are as follows:

Formulate 2 equations using the given information

1. xy = 5
2. x+y = -11

Substitute both equations, the answers are:

x = -10.525
y = -0.475

the sun's average surface temperature is 5780 k, while earth's average surface temperature is 288 k. how many times warmer, on average, is the sun's surface than earth's surface? use the equation below and round your answer to the nearest whole number.

Answers

Step-by-step explanation:

5780 / 288 = ~ 20 times warmer

In other words, 20 times the earth surface temp is the sun surface temp.
