Answer:
x = 8√5
Step-by-step explanation:
In the figure attached, there are three right angle triangles.
So, by Pythagoras theorem,
y²+ 4² = z²
y² + 16 = z²------(1)
Similarly x² = 16² + y²--------(2)
and (16 + 4)² = x² + z²
20² = x² + z²-------(3)
Now we put the value of z² from equation 1 to equation 3
20² = x² + y² + 16
x² + y² = 400 - 16
x² + y² = 384
y² = 384 - x²------(4)
Now we put the value of y² from equation 4 to equation 2
x² = 16² + 384 - x²
2x² = 256 + 384
2x² = 640
x² = 320
x = 8√5
Therefore x = 8√5 will be the answer.
Answer:$17,260 is how much more he will have to earn to pay for his degree!
Step-by-step explanation:First you have to multiply 7,215 with 4 and you get 28,860.Next you multiply 1,350 by 4 and you get 5,400.Then you add 5,400+4,200+2,000 and you get 11,600.Last but not least,you subtract 11,600 with 28,860 and you get $17,260!

Answer:
12.751
Step-by-step explanation:
13.9 - 1.149
--Subtract--
The word mean is a synonym for average. To find the average, you add all of the data, then divide by the amount of data received.
So, we add 2+4+3+5+4+6+5+3+6+3+7+0+8+1. That totals to 57. Then, we divide by 14 because there are 14 answers. The end result is 4.07, because we round up.
