Answer:3,-3
Step-by-step explanation:
difference of 2 squares
(x+3)(x-3)
x+3=0
x-3=0
x=3,-3
Answer:
21/100
Step-by-step explanation:
Letters: ABCDEFGHIJ 10 letters
Vowels: AEI 3
P (vowel)= vowels/ total = 3/10
No replacement ( assume the letter taken was a
Letters: BCDEFGHIJ 9 letters
Consonants : BCDFGHJ 7 letters
P(constant) = 7/10
P(vowel, no replacement, consonant) =P (vowel)*P(constant)
=3/10*7/10
=21/100
X2 + 14X = -49
+49
x2 + 14X + 49
(x2 + 14X + 7) + 49 - 7 = 0
(X+7)2 + 42 = 0
- 42
(x+7)2 = 42
*square root of both sides)
X + 7 = square root of 42
-7
X = -7 +/- square root of 42
x = -13.48
x = -0.52
and for b, without doing any work my guess is because there is a 0 under the radical, which gives you only one real solution
You already got the right answer there! That transformation is purely a reflection!
