According to the properties of operations, which equations are correct? Check all that apply. (A) 3a + 3b = 3(a + b)

(B) 6(g – 2h) = 6g – 2h

(C) –3c + 6d = 3(2d – c)

(D) –(4m + 8n) = –2(2m + 4n)

(E) 6u + 9v – 24w = 3(2u + 3v – 8w)

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

the answer is su.k.my? ? co.kc

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
