Step-by-step explanation:
(2x + 3)(2x + 3)
4x² + 6x + 6x + 9
4x² + 12x + 9
Answer:
(3x+2) ^2
x = -2/3
Step-by-step explanation:
9x^2+12x+4 = 0
We need to recognize that this is perfect squares
(a + b)2 = a^2 + 2ab + b^2;
Where a = 3x and b =2
a^2 = 9x^2 2ab = 2*3x*2 = 12x and b^2 = 2^2 =4
So we can factor this as (3x+2) ^2
If you want to solve
We can use the zero product property
(3x+2) ^2 =0
Take the square root of each side
3x+2 =0
Subtract 2 from each side
3x=-2
Divide by 3
3x/3 = -2/3
Which represents the polynomial written in standard form?
8x2y2 – + 4x4 – 7xy3
Answer:
Population is 34000 students
Sample is 770 students
Step-by-step explanation:
Population :In statistics, a population is the entire pool from which a statistical sample is drawn.
Sample: A sample refers to a set of observations drawn from a population.
We are given that 34,000 students attended the university.
Out of which a random sample of 370 male students and 400 female students was selected
So, Total students selected = 370+400=770
So, Population is 34000 students
Sample is 770 students
So, Option C is true.
Bru what type of math is this ? need more info smhh do better
