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
Answer:
{-0.36, 8.36) to the nearest hundredth.
Step-by-step explanation:
x^2 - 8x = 3
(x - 4)^2 - 16 = 3
(x - 4)^2 = 19
Taking square roots:
x - 4 = +/- √19
x = 4 +/- √19
x = {-0.36, 8.36} to nearest 1/100.
Answer:
45º
Step-by-step explanation:
diagonals bisect the corners of a square
the angle measure of the corners of a square is 90º
since the diagonal bisects the corners: 90÷2 = 45º
Answer:
Required equation : 
Weight of each of his checked bags = 15.5 kg
Step-by-step explanation:
Number of checked bags = 2
Backpack weight = 4 kg
The total weight of Carl's baggage = 35kg
Let w is the weight of each checked bag.
Weight of 2 checked bags = 2w
Weight of 2 checked bags + Backpack weight = Total weight of Carl's baggage
Subtract 4 from both sides.
Divide 2 from both sides.
Therefore, the weight of each of his checked bags is 15.5 kg.
