Answer:
13.5
Step-by-step explanation:
We need a number to complete
Since we have
And so the expanded square is
Cube root (27a^12)
Cube root 27 = 3 because
3 * 3 * 3 = 27
Cube root a^12 = a^4 because
a^4 * a^4 * a^4 = a^12
ANSWER
3a^4
Choice D is true. It is just another way to write the given function.
To confirm choices A through C, replace x as follows and do the math:
For A, let x = -3. Does it really yield -11?
For B, let x = 0. Does it really yield 5?
For C, let x = 1/2. Does it really yield 4?
Take it from here.
<span>X+3y=10
X-5y=-2
--------------subtract
8y = 12
y = 12/8 = 3/2 = 1.5
</span><span>X+3y=10
x = 10 - 3y
x = 10 - 3(1.5)
x = 10 - 4.5
x = 5.5
answer
x = 5.5 and y = 1.5 </span>
