Remove unnecessary parenthesis, and combine like terms
(3+i) + (5-2i)
3+i + 5-2i
8+i
you added 3+5 which is 5 and i-2i which is "i"
hope this helps.
Answer:
These are the properties of a parallelogram
• Opposite angles are equal
• The sum of all the angles is equal to 360 degrees
• Opposite angles are equal
• When the diagonals of a parallelogram are drawn, they bisect each other
• When a diagonal is drawn to separate the parallelogram into two, the two separate sides are equal when compared
• The sum of two adjacent angles in parallelogram is equal to 180 degrees
Step-by-step explanation:
For example,
Opposite angles (A and D) and (B and C) are equal
The sum of all the angles give 360 degrees, angles A + B + C + D = 360
Side AB is equal to side CD (/AB/ = /CD/)
The sum of adjacent angles A and C gives 180 [angles (A + C ) = 180]
Choose the option similar to any of these properties in the question

Step-by-step explanation:
just multiplied the powers
Answer:
24 sq cm
Step-by-step explanation:
According to theorem of area if parallelogram and triangle, if the triangle and a parallelogram lie between two parallel line and their base is same then, the area of triangle is half of the area of the parallelogram. so here the parallelogram PTRS and the triangle PTR lie between same parallel lines PT and RS and base is also same PT. so area of PTR is 12sq cm. Again, triangles PTR and TRQ lie between same parallel lines PQ and SR and same base PQ. so their area also same that is 12 sq cm. Now, area of PQR = area of PTR + area of TRQ = 12 + 12 sq cm = 24 sq cm.
You are given the area of both cupboards.
The total area would be found by adding the two areas together:
3a^2 − 5y + 15 + 4a^2 + 5y + 5
Combine like terms:
3a^2 + 4a^2 = 7a^2
-5y + 5y = 0y
15 +5 = 20
The area of both cupboards would be 7a^2+20
