5. A team of mountain climbers makes camp 1.48 kilometers above sea level. They climb another 2.91 kilometers to the mountain's peak. How tall is the mountain?

4.3068

Step-by-step explanation:

so what you do is 1.48 x 2.91

= 4.39km

Step-by-step explanation:

Camp distance = 1.48Km

Distance travelled afterwards = 2.91km

Mountain Height = total distance travelled

So total distance = 1.48 + 2.91  

                         = 4.39km > final answer

b

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
