Answer:
A...similar triangles
Step-by-step explanation:
option b... the two triangles are not congruent
option c... the area of ∆AED= 3, ∆ACB= 12.. half of 12 is 6.. wrong
option d. perimeter of ∆AED= 8.60, area of ∆ACB = 12... one fouth of 12 =3. wrong.
option A.. similar triangles have the same shape but they necessarily don't need to have the same size. ... correct! both triangles are right angled triangles.
note.. perimeter is summation of all sides..
solving unknown side use Pythagoras formulae
hyp= √ height (sq) + base (sq)
area of ∆ = 1/2 * base * height...

Answer:
A: x+5
B: 4x-1
Step-by-step explanation:
4x^2+19x-5
(4x ) ( x )
We know that 1 will be positive and 1 will be negative.
Our choices for the numbers are 5 and 1
4*5 -1 = 19
(4 x - 1) (x + 5)
Hello there!
Answer: C
Step-by-step explanation:
C) -2 + 2 = 2 + (-2)
Why?
Well, we know that when we have a negative sign and a positive sign, we ended up having negative.
Thus, 2 + (-2) = +2 - 2 which is the inverse of the other side.
I hope this answer helps you. As always, it is my pleasure to help students like you!
