Answer:
The coefficient of the 2nd term of trinomial is 18.
Step-by-step explanation:
You can expand in a faster way by using the formula, (a+b)² = a²+2ab+b² :
(3x+3)² = (3x)² + 2(3x)(3) + 3²
= 9a² + 18a + 9
OR
You can expand it by doing step by step :
(3x+3)² = (3x+3)(3x+3)
= 3x(3x) + 3x(3) + 3(3x) + 3(3)
= 9x² + 9x + 9x + 9
= 9x² + 18x + 9
B inverse you swap x and y
X^2 + 4x = 0
x^2 + 4x + 4 = 0 + 4
(x + 2)^2 = 4
See I have had bad days in school Bc of so much homework and writing but thissssss
Answer:
$1,855
Step-by-step explanation:
Rent per year = $15.90 psf
Hence,
Rent per month = 15.90/12 psf = $1.325 psf
Rent of the store per month
= 1400 * $1.325 psf
= $1,855
