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:
Step-by-step explanation:
9a = 7
a= 7/9
Hope this helps ^-^
Step-by-step explanation:
She should take atleast 12 sessions
So 12 x 50 = 600
600 + 200 = 800
Answer: How do you find you four consecutive odd integers such as three times the sum of the first and the second is 15 less than the fourth?
Step-by-step explanation: So, the normal consecutive integers numbers are: 2,3,4,5. And the even consecutive integers numbers are: 2,4,6,8. And the odd consecutive integers are: 3,5,7,9. Consecutive integers formula are the algebraic representations of the consecutive integers. The formula to get a consecutive integer is n + 1.
Same as above, 7 is one of 4 consecutive integers, then the result is only 4 cases:
, 5, 6, 7
, 6, 7, 8
, 7, 8, 9
, 8, 9, 10
Hope this helps.
