Factorize both the numerator and denominator then equate to zero ...you'll get X
Answer:
D. 8
Step-by-step explanation:
y varies jointly as x and z
y = k(xz)
-------------------------
Find k, the constant of variation
y = 12 when x = -2 and z=3
12 = k(-2 * 3)
12 = k(-6)
k = -2
-------------------------
find y when x is 4 and z is -1
using k = -2
y = -2(4 * -1)
y = -2(-4)
y = 8

Answer:
Explanation:
To find the difference (3c - d)² you should recognize that it is the square of a difference of two terms.
The square of the difference of two terms is a special case that you should remember: it is equal to the square of the first, minus twice the product of the first and second, plus the square of the second:
For the binomial (3c - d)² you have that:
Thus:
- (3c -d)² = (3c)² - 2(3c)(d) + d² = 9c² -6cd + d² ← answer
