Step-by-step explanation:
⅔ + ¾
→ make the denominator equal of both the fraction
= 2/3 × 4/4 = 8/12
= 3/4 × 3/3 = 9/12
hence,
8/12 + 9/12
= 8 + 9/12 = 17/12

Answer:
b = 2
Step-by-step explanation:
Given
2b + 5 = 9 ( subtract 5 from both sides )
2b = 4 ( divide both sides by 2 )
b = 2
1. discriminant = b^2 - 4ac = (-5)^2 - (4 x 1 x 7) = 25 - 28 = -3 [imaginary root]
2. discriminant = (-5)^2 - (4 x 1 x -4) = 25 - (-16) = 25 + 16 = 41 [real and irrational root]
3. discriminant = (8)^2 - (4 x 16 x 1) = 64 - 64 = 0 [double root]
