Given:
Teddy has two sisters. One of them is 3 years younger than Teddy, the other one is 7 years younger than her only brother.
To find:
The age of older sister at the time when the younger sister was born.
Solution:
Let the age of Teddy be x.
One sister is 3 years younger than Teddy.
Age of one sister = x-3 years
The other one is 7 years younger than her only brother. It means other sister is 7 years younger than Teddy.
Age of other sister = x-7 years
Clearly (x-3) > (x-7). So, difference between the ages of sisters is
Therefore, the age of older sister is 4 years when the younger sister was born.
I think it’s A. 12mm Bc if u take away 4mm from the 10mm it gives u the triangles base which is 6mm and then taking away 8mm from 12mm gives u 4mm which would be the height
To find the area of a triangle u need the base and height
Triangle Area= 1/2bh
1/2(4)(6)= 12
Answer:
g(x) = 7(-x)³
Step-by-step explanation:
The cubic parent function is given as; f(x) = x³
Now, we are told that it reflects across the y-axis. This means that the new function will take the form;
g(x) = f(-x)
Thus, the new function is;
g(x) = (-x)³
Now,we are told that this new function stretches by multiplying by 7. Thus, we now have;
g(x) = 7(-x)³
Hi!
The GCM of 14 and 28 is 7. 7 goes into 14 2 times, and goes into 28 4 times. So...
2/4
Which can be simplified further to 1/2
The answer is 1/2
Hope this helps! :)
