x² + bx - 81
there are 2 formula that fit this equation :
>> x² - a² = (x+a)(x-a)
or
>> x² + 2ax² + a² = (x+a)(x+a)
because the last value of our equation is negative value therefore we have to use the first formula >> x² - a² = (x+a)(x-a)
step:
x² + bx - 81
x² + bx - 9²
because we have to follow the first formula x² - a² therefore bx = 0
x² + bx - 9²
bx = 0
b = 0
Answer:
Dividing 4x^2 - 13x + 8 by x + 5 or x - (-5), in synthetic division form:
-5) 4 | -13 | 8
↓ 4 x (-5) (-5) x (-33)
4 -33 173
=> Quotient is 4x - 33 and remainder is 173
=> (4x^2 - 13x + 8)/(x + 5) = (4x - 33) + 173/(x + 5)
Hope this helps!

Answer:
P = 9x + 22
Step-by-step explanation:
Perimeter = sum of all sides
P = (3x + 11) + (3x + 11) + (3x)
P = 9x + 22
I hope this helps! God bless
