Answer:
72 √2
Step-by-step explanation:
3 √2 can be left alone
2√8 can be simplified to 2(2) √2 or 4√2
and those two can be multiplied to get 24
√3 x √6 = 3√2
and 3√2 x 24 will =
72√2
Answer:
A
Step-by-step explanation:
not 100% sure use my answer with caution
A zero, or a solution of the quadratic function is c) x = 6 1/3
Write -54x as a difference
9x^2 + 3x - 57x - 19
Factor 3x out
{ 9x^2 + 3x } - 57x - 19
3x (3x + 1)
Factor -19 out
3x (3x + 1) -19 (3x + 1)
Group the equations
( 3x - 19 ) ( 3x + 1 )
Solve for the zeroes
(3x+1) = 0
-1 -1
3x = -1
3x / 3 = x
-1 / 3 = -1/3
x = - 1/3
(3x - 19) = 0
+19 +19
3x = 19
3x / 3 = x
19 / 3 = 6 1/3
x = 6 1/3
Answer:
Step-by-step explanation:
y = 2*3^x
x = 1
y = ?
y = 2*3^1
y =2 * 3
y = 6
The answer is the first graph.
If we pay $8.28 for 18 stamps we can find the price of one stamp by dividing by 18.
So, the price of one stamp will be
$8.28 / 18 = $ 0.46
To find the price of 12 stamps we have to multiply by 12 and finally find
$0.46 * 12 = $5.52
Hence, the cost of 12 stamps is $5.52
