Equivalent expressions are expressions of equal values
The simplified expression of (3 - 4i) + (7 - 6i) is ![10- 10i](https://tex.z-dn.net/?f=10-%2010i)
The expression is given as:
![(3 - 4i) + (7 - 6i)](https://tex.z-dn.net/?f=%283%20-%204i%29%20%2B%20%287%20-%206i%29)
Remove brackets in the above expression
![3 - 4i + 7 - 6i](https://tex.z-dn.net/?f=3%20-%204i%20%2B%207%20-%206i)
Rewrite the expression by collecting the like terms
![3 + 7- 4i - 6i](https://tex.z-dn.net/?f=3%20%2B%207-%204i%20%20-%206i)
Next, evaluate the like terms
![10- 10i](https://tex.z-dn.net/?f=10-%2010i)
Hence, the simplified expression of (3 - 4i) + (7 - 6i) is ![10- 10i](https://tex.z-dn.net/?f=10-%2010i)

Step-by-step explanation:
Answer:
L and W +5
Step-by-step explanation:
A1=15*12=180
A2=160+A1=340
340 factors
340,1,2,170,5,..., 20,17
20*17=340
|15-20|=5
|12-17|=5
add 5
Answer:
![(1) = 38\°](https://tex.z-dn.net/?f=%281%29%20%3D%2038%5C%C2%B0)
![(2) = 90\°](https://tex.z-dn.net/?f=%282%29%20%3D%2090%5C%C2%B0)
![(3) = 90\°](https://tex.z-dn.net/?f=%283%29%20%3D%2090%5C%C2%B0)
![(4) = 38\°](https://tex.z-dn.net/?f=%284%29%20%3D%2038%5C%C2%B0)
Step-by-step explanation:
The diagonals of a rhombus are perpendicular to each other, so angles (2) and (3) are equal 90°.
To find angle (1), we can use the sum of internal angles in the left triangle with angles 52°, (1), and (2):
![52 + (1) + (2) = 180](https://tex.z-dn.net/?f=52%20%2B%20%281%29%20%2B%20%282%29%20%3D%20180)
![(1) = 180 - 52 - 90](https://tex.z-dn.net/?f=%281%29%20%3D%20180%20-%2052%20-%2090)
![(1) = 38\°](https://tex.z-dn.net/?f=%281%29%20%3D%2038%5C%C2%B0)
The diagonals of a rhombus bisects the angles, to the angle next to the angle of 52° is also 52°, then, in the upper triangle, we have:
![52 + (4) + 90 = 180](https://tex.z-dn.net/?f=52%20%2B%20%284%29%20%2B%2090%20%3D%20180)
![(4) = 38\°](https://tex.z-dn.net/?f=%284%29%20%3D%2038%5C%C2%B0)
