Answer:
9x² -6xy +y²
Step-by-step explanation:
The square of the binomial can be written directly using the relationship ...
(a +b)² = a² +2ab +b²
where you have a=3x and b=-y.
area = (3x -y)² = (3x)² + 2(3x)(-y) + (-y)²
area = 9x² -6xy +y²
Answer:
29 degrees
Step-by-step explanation:
Both angles are the same.
Answer: 439,824 ft
Step-by-step explanation: the | means it is equal to so there is one on 7ft so the one without a number will be 7ft
Area is LxW
so 7x6x8x11x17x7=439,824
not sure if it’s correct tho but i guess I helped
Answer:
x³ + 2x² - 19x - 20
Step-by-step explanation:
x + 1 = 0
x = -1
Substitute x = (-1) in the polynomial
x³ + 2x² - 19x - 20 = (-1)³ + 2*(-1)² - 19 *(-1) - 20
= -1 + 2 +19 - 20
= -1 - 20 + 2 + 19
= -21 + 21 = 0
So, (x + 10 ix a factor of x³ + 2x² -19x - 20
