Answer:
59 cm
Step-by-step explanation:
The area is the product of length and width. Using the given numbers, we have ...
A = LW
4779 cm² = (81 cm)W
W = (4779 cm²)/(81 cm) = 59 cm
The width of the window is 59 cm.
All you have to do is the amount she bought divided by 0.05 and then add the answer you get to the amount she bought each time
Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
