Do you have an image of the question?
Answer:
2A/ (b1-b2) =h
Step-by-step explanation:
A = 1/2 (b1-b2) *h
Multiply each side by 2
2A = 2 *1/2*(b1-b2) *h
2A = (b1-b2) *h
Divide by (b1-b2)
2A/ (b1-b2) = (b1-b2)/(b1-b2) *h
2A/ (b1-b2) =h
Answer:
You have my profile picture
Step-by-step explanation:
Increase- to be more significant in value, to be of more worth, to have a larger quantity.
Basically, if I said I added 2 to 5, that would be an increase.
2+5=7 7 is bigger than 5.
If I subtracted 2 from 5, that would make a decrease in value.
5-2=3 3 is smaller than 5.
I hope this helps!

Answer: Yes these triangles are similar
Step-by-step explanation:
First lets write down what we know just to make life easier
x=9
TL should be similar to CH
LY should be similar to KH
The angles should be equal due to SAS
So the first thing we know is true is the fact that they have equal angles. Now we have to find out if the sides are similar or if they change by the same ratio to the other. If TL is similar to CH and TL=25 and CH=10 what is the change in size or dilation. Division should do the trick so 25/10=2.5 so TY is greater than CH by a factor of 10. Which means that LY should also be greater than KH by a factor of 2.5. If we are told that x=9 than side LY or 4(9)-1=35 and KH 9+5=14
So side KH is 14 and LY is 35. Now to check if they are similar then KH should be greater by a factor of 2.5. If this is not true than the sides are not similar. 35/2.5=14
Since 35 divided by 2.5 is 14 we can tell both sides TL and LY are greater than KH and CH by a factor of 2.5
Hope this helps.
