Answer:

The answer to your question is: letter B.

Step-by-step explanation:

Solve for d 4 − d < 4 + d

Add -d in both sides 4 - d - d < 4 + d - d

Simplify 4 - 2d < 4

Substract 4 in both sides 4 - 4 - 2d < 4 - 4

Simplify - 2d < 0

Divide by -2 both sides -2/-2 d > 0 / -2

Simplify d > 0 Change the inequality

PEMDAS (right to left) (Parentheses, exponents, Multiplication/Division, Addition/Subtraction) or Please Excuse My Dear Aunt Sally is what I was taught to use.
1.[(-4)+{-2}]*(-5)^2-9; divide 8 by -4 (it is the innermost parentheses problem)
2. [(-6)]*-5^2-9; next innermost parentheses problem
3. [(-6)]*25-9; exponents
4. -150-9; multiplication
5. -159; subtraction/addition depending on how you want to look at it

In the diagram, AE = 2AC and ∠BAC ≅ ∠DAE. What additional information is necessary to prove that ΔABC is similar to ΔADE, using

ss7ja [257]

Since you want to use the SAS theorem, you must find sides that are either side of angles BAC and DAE. You have already made use of sides AE and AC, so the other sides you need to choose are AB and AD. The appropriate relationship for similarity is ...

... AD = 2AB

since you want the sides of triangle ADE to be twice then length of those in triangle ABC.
