São pes das perpendiculares traçadas de para o plano nos pontos A Na figura seguinte esta representada uma reta paralela ao plano
Sabendo que CD = 6 - AC = 3V5, então a retar dista do plano :
(A) 315
(D) 3V5+6
(B) 6​

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
