Answer:
(a)
Step-by-step explanation:
To determine if the points are a solution to the equation.
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then they are a solution.
(2, 5)
- 3(2) + 4(5) = - 6 + 20 = 14 ← True
(4, 6)
- 3(4) + 4(6) = - 12 + 24 = 12 ← False
Thus (2, 5) is the only solution to the equation → (a)
Ans is 392 mm and approx 400mm as perimeter of semi circle is pi r which is 22/7*16 + 40 mm which is the total of the two side of the triangle given.

Answer:
The answer to your question is: d) 0.46x10^-4
Step-by-step explanation:
(1.15x10⁻⁷) / (2.5x10⁻³)
First, divide 1.15 by 2.5 1.15 / 2.5 = 0.46
Second, subtract the power -7 - (-3) = -7 + 3 = -4
Finally, express the number 0.46 x 10⁻⁴
a) 4.6x10^-10
b) 0.46x10^-3
c) 4.6x10^-3
d) 0.46x10^-4
