Answer:
33
Step-by-step explanation:
396/x - 10 = -22
add 10 to each side
396/x = -12
multiply both sides by x
396 = 12x
divide both sides by 12
33 = x
X+90 = length
x=width
4x+180=400
4x=220
x=55
The width is 55 yards and the length is 145 yards
Answer:
9 yards
Step-by-step explanation:
3 yards make 2 skirts
2x3=6
3x3=9
9 yards make 6 skirts
<span>f(x)=x^3-4x^2+2x+4, we know that f(2)=8-16+4+4=16-16=0
and we can write f(x)= (x-2)Q(x) so Q(x) = f(x) / (x-2)=x²-2x-2
</span><span>x²-2x-2=0 delta = (-1)²- (1).(-2) =1+2=3
</span>x=1-sqrt3 or <span>x=1+sqrt3
finally the zeros are x=2, </span>x=1-sqrt3 or <span>x=1+sqrt3 </span>
