Let
x-------------> amount added <span>to each side
</span>A-------------> area increased----------> 84 ft²
we know that
A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x²
50+15x+x²=84----------> x²+15x-34=0
<span>solving the second order equation
</span>x1=-17
x2=2
the answer is x=2 ft
Tyra used 6 kilograms total to fill up all bird feeders.
X<-7 so the answer would be greater*
Answer:
smal and blurry
Step-by-step explanation:
-4.4(s - 2) + 6.9s = 14.8
Distribute -4.4 into the parenthesis:
-4.4s + 8.8 + 6.9s = 14.8
Combine like terms:
2.5s + 8.8 = 14.8
Subtract 8.8 from both sides of the equation:
2.5s + 8.8 - 8.8 = 14.8 - 8.8
2.5s = 6
Divide both sides by 2.5:
2.5s/2.5 = 6/2,5
s = 2.4
s =
