Answer:
Ada is correct.
Step-by-step explanation:
If you use the Pemdas rule, you know that you need to get rid of the brackets first by using distributive property of multiplication.
2(4x - 3) + 6
2(4x) - 2(3) + 6
8x - 6 + 6
8x + 0
8x
Answer:
area=6
perimeter=36
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>In right triangle sum of two angles is 90°</u>
- 4x + x = 90°
- 5x = 90°
- x = 90°/5
- x = 18°
<u>Angle y is exterior angle and equals non-adjacent interior angles</u>
- y = 4x + 95° =
- 4*18° + 95° =
- 72° + 95° =
- 167°
To determine the answer of Part A draw the equilateral triangle and the to determine the coordinates of of the third charge use that triangle.
To calculate the gravitational field strength in part B from each of the charges use the following equation.
E=kcq/r2
If you would add those values then you can use the symmetry about the y axis to make the vector addition a litter easier.<span />
