Answer: She is not correct, because she must multiply the base and the height of the triangle and then divide by 2.
Step-by-step explanation:
1. The formula for calculate the area of a triangle is shown below:
Where 
is the base and 
is the height.
2. Then, if she applied the method she reasoned, she'd obtain the following area:
3. But actually, Magda should multiply the base and the height of the triangle and then divide by 2. Then, the correct area is:
Answer:
correct answer is B
Step-by-step explanation:
comparing the speed at which the three cars travel and also considering the fact that they travel at a constant speed without increase or decrease in speed or acceleration, it gives B the highest speed at 55h per day
thank you.
Answer:
u1 = 1
u6 = 31
un = 1 + 6(n - 1)
Step-by-step explanation:
Sn = 3n² - 2n
u1 = S1
3(1)² - 2(1)
3 - 2
1
u6 = S6 - S5
[3(6)² - 2(6)] - [3(5)² - 2(5)]
96 - 65
31
un = a + (n - 1)d
u6 = a + 5d
31 = 1 + 5d
5d = 30
d = 6
un = 1 + 6(n - 1)
(0,-4.69) i hope this is correct
