Answer:
6 plus 4 i times the square root of 5
Step-by-step explanation:
The given statement can be written as:
6+√-80
To solve √-80 re-write -80 as -1 * 80
Now √-80 =√-1 * 80
Now we can write it as:
6+ √-1 * √80
We know that √-1 = i
Thus it becomes:
6+ i√80
Now find the square root of 80
80 does not have a perfect square root
Its square root can be found as 80 = 4*4*5
Then,
6+i√4*4*5
Notice that 4 makes a pair.. So we will write it outside the square root
6+1*4√5
We will write it as:
6+4i√5
Thus the correct option is 6 plus 4 i times the square root of 5....
Answer:
8*7/4=7x
56/4=7x
14=7x
x=2
Step-by-step explanation:
Answer:
a(b + c) = a • b + a • c
=> 8(3 + 4) = 8.3 + 8.4 = 24 + 32

Answer:
x=46 4/5, x=46.8
Step-by-step explanation:
To find x-intercept/zero, substitute y=0
-222=5x-3(-7*0-4)
-222=5x-3(-7*-4) Solve
x= -234/5
x=46 4/5, x=46.8
Student c was close to average
