Answer: 2(12+8) +3
Step-by-step explanation: In the morning they made 12 + 8 airplanes = (12 + 8)
In the afternoon they doubled the number that they made in the morning = 2 (12 + 8)
Finally, you would add 3 to this for the ones that her brother made = 2 (12 + 8) + 3
Thomas is 29 and Huilan is 37. 29+37= 66
Answer:
x = 3
y = 2
Step-by-step explanation:
<u>GIVEN :-</u>
- PQ = 2y + 3
- QR = 4y + 1
- RS = y + 5
- PS = 4x - 3
<u>TO FIND :-</u>
- The values of x & y for which PQRS will be a parallelogram
<u>FACTS TO KNOW BEFORE SOLVING :-</u>
In a parallelogram , pair of opposite sides are always equal in length.
<u>SOLUTION :-</u>
PQRS will be a parallelogram only when :-
1) Assume that PQ = RS.
∴ For y = 2 , PQ = RS.
2) Now, assume that PS = QR.
(Put y = 2 in the equation)
∴ For x = 3 , PS = QR.
<u>CONCLUSION :-</u>
For x = 3 & y = 2 , PQRS is a parallelogram.
