2(a+b)=c
2a + 2b = c
2b = c - 2a
b = (c - 2a)/a

answer
D. b = (c−2a)/2 ; distribute 2 to get 2a+2b, subtract 2a, then divide by 2.

The extensions of the legs AB and CD of a trapezoid ABCD intersect at point E. Find the lengths of the altitude of △AED drawn to

Gnom [1K]

let's call G the intersection point of EF & BC.

according to the thales' theorem:

$\frac{eg}{ef} = \frac{bc}{ad}$

and EF= EG+GF=EG+3

$\frac{eg}{eg + 3} = \frac{7}{21}$

$21eg = 7eg + 21$

$14eg = 21$

$eg = \frac{21}{14} = \frac{3}{2} = 1.5$

length of the altitude of △AED=EF

EF=EG+GF=1.5+3=4.5

The rectangles shown below are similar figures. Use the properties of similar figures to solve for the value of s.

Sergeu [11.5K]

Answer:

s = 3

Step-by-step explanation:

we know the rectangles are similar

2 × __ = 16

s × __ = 24

so,

16÷2 = 8

2 × 8 =16

s × 8 =24

then,

24 ÷ 8 = s

3 = s

2 × 8 = 16

3 × 8 =24

hoped i helped :)
