Answer: E
Step-by-step explanation:
(3x^2 - 8) (3x^2 + 8)
You can get to the original equation by:
3x^2 * 3x^2 = 9x^4
-8 * 8 = - 64
9x^4 - 64
Answer:
E. (3x^2-8)(3x^2+8) is the correct answer.
Step-by-step explanation:
To factor this we use the differenceoftwosquaresformulabecause there are no common terms here.
9x^2-64
The square root of 9x^2= 3x^2
The square root of 64 is 8
(3x^2-8)(3x^2+8)
= 9x^2-64
You get back the answer. So it's correct.
−1 + 10i
1 + 6i
1 + 10i
The given expression simplified can be written as -1 + 6i. which is the correct answer that would be an option (A).
A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib,
where a, and b are real numbers and i is an imaginary number.
To simplify the expression (3 + 8i) − (4 + 2i), we need to subtract the two complex numbers. To do this, we subtract the real parts and the imaginary parts separately.
The real part of the first complex number is 3, and the real part of the second complex number is 4.
Subtracting these gives us -1.
The imaginary part of the first complex number is 8, and the imaginary part of the second complex number is 2.
Subtracting these gives us 6. Therefore, the simplified expression is (-1) + (6i) = -1 + 6i.
Therefore, the correct answer is: -1 + 6i.

D. rolling a 5, rolling an odd number
Answer:
Step-by-step explanation:
y + 4 = 11/6 (x+1)
y − 1 = 6/11 (x−4)
y + 1 = 6/11 (x+4)
The point-slope form:
m - slope
(x₁, y₁) - point
The formula of a slope:
We have the points (7, 5) and (-4, -1). Substitute:
