Answer:
two-hundred and three.
Step-by-step explanation:
its pretty simple, the way i did it was write down your multiples of 3 starting from 20. 20+23+26+29+32+35+38. add that together to get 203 minutes for the week.
x = the granddaughter's age x + 2 = the grandson's age
x + x + 2 ≥ 12 Collect like terms.
2x ≥ 12 Divide both sides by 2.
x ≥ 6 years
x + 2 ≥ 8 years
ANSWER
The length of
![A'B'=14.04 \: units](https://tex.z-dn.net/?f=A%27B%27%3D14.04%20%5C%3A%20units)
EXPLANATION
The object length given to us is,
![|AB|=10.8 \: units](https://tex.z-dn.net/?f=%20%7CAB%7C%3D10.8%20%5C%3A%20units)
The scale factor of the dilation is,
![k = 1.3](https://tex.z-dn.net/?f=k%20%3D%201.3)
The image length can be calculated using the formula
![|A'B'| = k \times |AB|](https://tex.z-dn.net/?f=%20%7CA%27B%27%7C%20%3D%20k%20%5Ctimes%20%20%7CAB%7C%20)
We substitute the given values into the formula to get,
![|A'B'| = 1.3\times 10.8](https://tex.z-dn.net/?f=%20%7CA%27B%27%7C%20%3D%201.3%5Ctimes%2010.8)
We multiply out to obtain,
Since it is an equilateral triangle, all of the sides are the same length.
So, x=14 :)
Hope this helps!
Unless you meant -1/2x+2 the top answer is correct. If you meant the other it is -1/2(d/dx(x+2), which results in -1/2(1) or -1/2.
