Answer:
Total Dolls would Evelyn have had if she had not lost them = 9 Dolls
Step-by-step explanation:
As given,
Total dolls Evelyn had = 9
Total dolls lost = 
× 9 = 3
So, Now
Evelyn had total dools after lost = 9 - 3 = 6
If she had not lost te dolls , then she had 3 dolls more
∴ we get
If she had not lost any dolls , Evelyn had total dolls = 6 + 3 = 9
So, The answer would be :
Total Dolls would Evelyn have had if she had not lost them = 9 Dolls
The 5 is represented as 50. The number is in the tens place, and 5 in the tens place means 50.
Answer: x = 6 plus-or-minus 3 StartRoot 10
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 12x + 36 = 90
Rearranging the equation so that it takes the the standard form of
ax² + bx + c, it becomes
x² - 12x + 36 - 90 = 0
x² - 12x - 54 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = - 12
c = - 54
Therefore,
x = [- - 12 ± √(- 12² - 4 × 1 × - 54)]/2 × 1
x = [12 ± √(144 + 216)]/2
x = [12 ± √360]/2
x = (12 ± 6√10)/2
x = 6 + 3√10
It is definitely D because on part 1 n=24n+20 and if n equals 0 than 24 (0) +20= 20 and that is true. on part 2 if n =0 than 24 (0)+ 20 (0-1)=20 than 20 (-1)=20 -20= 20. that statement is false because-20 does not equal 20. AND for part 3 n=1 and f (1-1) + 24= 44 so f (0) + 24 =44 and keep in mind f (0) equals 20 so 44=44 because 24+20 is 44. so that is a true statement too
