Answer:

32 (degrees)

Step-by-step explanation:

Triangles AED and ACB share a common angle A.

Two of the corresponding sides have the same ratio: AB=AD+DB=2AD, AC=AE+EC=2AE

Therefore the triangles are similar.

Therefore the corresponding angles are congruent, in particular

∠AED ≅ ∠ACB

∠ECF is just another name for ∠ACB

∠AED ≅ ∠ECF

So their measures must be the same,

m∠AED = m∠ECF = 32°

Which expression is equal to 4(2+3)?<br> A. 8 + 3<br> B. 4 + 5<br> C. 2 + 12<br> D. 8 + 12

Blababa [14]

First, answer the problem in the parentheses. 2 + 3 is 5. 5 x 4 is 20. Now, we are going to find the question that has an answer of 20. A = 11 so it cant be that one. B is 9 so not that one, either. C is 14 so not that one, but D = 20 so we have found the answer. D is the correct answer.

the domain is gonna be ur x values and ur range is gonna be ur r(x) values

the domain has to do with the number of t-shirts.....and it can range from 0 to 25.......so it would be written as : [0,25]...include the brackets....not parenthesis...or all whole numbers from 0 to 25

the range has to do with the money made....and it can range from : -100 to 200....so it would be written as : [ -100,200] ..use brackets and not parenthesis.
