So first calculate root of 3 which is 1.732
Next multiply by 8 to get 13.856
Hope this helps:)
A. 4y(2y + 5) = 4y(2y) + 4y(5) = 8y² + 20y
B. 7a(3a + 8b) = 7a(3a) + 7a(8b) = 21a² + 56ab
C. 13x³(3y + 2x²) = 13x³(3y) + 13x²(2x²) = 39x³y + 26x⁴ units²
D. 7m²(3m - 5) = 7m²(3m) - 7m²(5) = 21m³ - 35m² units²
Ok done. Thank to me :>
Tan² B = 4
(tan B)² = 4
tan B = ±2
Basic Angle
= tan^-1 2
= 63.4° (1dp)
B = 63.4°, 116.6°, 243.2°, 296.6°
Assuming you're actually supposed to present your answers in 0dp, then all answers apply.
Solution:
1) m is atleast 25
"at least" means greater then or equal to
Therefore,
2) p is less than 48
3) h is atmost 56
"at most" means less than or equal to
4) k is no greater than 9
Which means k is less than or equal to 9
5) w is no less than 0
Which means, w is greater than or equal to 0
