Answer: 3. Distributive
Step-by-step explanation:
3(x -2y) = 3x - 6y To get from left to rigth, you have to multiply them which is the same as distribitue.
3(x) - 3(2y) = 3x - 6y
The value of X is 12. STEP 1) distribute the 1.50 to the X and 6 to get 1.50x and 9 STEP 2) subtract 9 from 27 to get 18 STEP 3) divide 18 by 1.5 and you get X=12
Answer:5 inches
Step-by-step explanation:
Let l the length of a side edge and d the length of diagonal of a side
so than using sin we can writing
sin45 = l/d
sqrt2 /2 = l/d
and given that this area s=5sqrt2 what is equal l*d so in this case there are
l/d = sqrt2 /2
l*d = 5sqrt2 => l = 5sqrt2 /d and this subtituted in place of l inside the first equation we get
(5sqrt2 /d)/d = sqrt2 /2
5sqrt2 /d^2 = sqrt2 /2
10sqrt2 = d^2 *sqrt2 divide both sides by sqrt2
10 = d^2
d = sqrt10 so than d = sqrt10 result l = 5sqrt2 /sqrt10 = 5sqrt20 /10 =
= sqrt20 /2 = 2sqrt5 /2 = sqrt5
l = sqrt5
d = sqrt10
so area total del cubo = 6*l^2 = 6*(sqrt5)^2 = 6*5 = 30 unit squared
so choice d) is right sure
hope this will help you
Melanie: <span> (2010, 48) and (2013, 59)
Equation will be
y = (59-48)/(2013-2010) * (x - 2010) + 48
</span>>> y = (11/3) * (x - 2010) + 48
>> y = (11/3)x - (11/3)*2010 + 48
>> y = (11/3)x - 7370 + 48
>> y = (11/3)x - 7322
Tracy: (0, 48) and (3, 59)
Equation will be
y = (59-48)/(3-0) * (x - 0) + 48
>> y = (11/3) * x + 48
>> y = (11/3)x + 48
The slopes of both the equations are same, but y-intercept are different. Because Melanie used actual years (variable x), whereas Tracy used years since 2010.
