Answer:
Option D is correct, i.e. (4xy - 3z)² = 16x²y² -24xyz + 9z², a perfect square trinomial.
Step-by-step explanation:
Given the expression is (4xy - 3z)².
Using the formula, (a - b)² = a² -2ab +b².
(4xy - 3z)² = (4xy)² -2(4xy)*(3z) + (3z)²
(4xy - 3z)² = 16x²y² -24xyz + 9z²
It is a trinomial expression and we got it from squared binomial.
Hence, option D is correct, i.e. (4xy - 3z)² = 16x²y² -24xyz + 9z², a perfect square trinomial.
Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621

Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102
It should be 95 I believe. Sorry if I’m wrong
Answer:
D) y = 2x − 8
Step-by-step explanation:
Use the Distributive Property to convert from <em>Point-Slope</em><em> </em><em>Form</em><em> </em>to <em>Slope-Intercept</em><em> </em><em>Form</em>:
y − 4 = 2(x − 6)
y − 4 = 2x − 12
+ 4 + 4
