Answer:
no
Step-by-step explanation:
1). 7 x 10^6 - 5.3 x 10^6 = 7.0-5.3 (×10^6)
= 1.7 × 10^6
2). 3.4 x 10^4 + 7.1 x 10^5 = 3.4+71 (×10^4)
= 74.4 × 10^4 = 7.44 × 10^5
Answer:
w = - 16.06 or w = 2.06
Step-by-step explanation:
Given
w² + 14w - 33 = 0 ( add 33 to both sides )
w² + 14w = 33
To complete the square
add ( half the coefficient of the w- term )² to both sides
w² + 2(7)w + 49 = 33 + 49, that is
(w + 7)² = 82 ( take the square root of both sides )
w + 7 = ± ( subtract 7 from both sides )
w = - 7 ± , that is
w = - 7 - ≈ - 16.06 or w = - 7 + ≈ 2.06
2 yards to decimeters
1 yard = 9.144 decimeters
2 yards = ? decimeters
2 × 9.144 = 18.288
2 yards = 18.288 decimeters
