Answer:
116 centimeter squared
Step-by-step explanation:
La²+8La+16 = La²+70
Step-by-step explanation:
8La+16 = 70
8La=70-16
La=54/8
La= 6.75
Area b = (6.75+4)*(6.75+4)
Area b = 10.75*10.75
Area b =115.563
Answer:
The correct option is 70
Step-by-step explanation:
It is a right triangle so we will use Pythagorean theorem to find AB:
We have One side = 24 and hypotenuse = 24+50 which is 74
Now apply Pythagorean theorem:
AB = √(74)²-(24)²
AB = √5476-576
AB= √4900
Take the square root of 4900.
AB= 70
Thus the correct option is 70....
A car travels 440km in 15.4 hours -> In 1 hour, the car travel 1/(15.4) the distance.
So in an hour, the car travel : 440 x 1/(15.4) = 28.5714285714... (round to 29)
So, the average speed of the car is approximately 29 km/h
