The numbers are "x" and "y"
Therefore, we can suggest this system of equations:
x+y=10 ⇒x=10-y
xy=-60
Solve this system of equations by substitution method.
(10-y)y=-60
10y-y²=-60
y²-10y-60=0
Solve this square equation:
y=[10⁺₋√(100+240)]/2=(10⁺₋2√85)/2=5⁺₋√85
We have two solutions:
y₁=5-√85 ⇒x₁=10-(5-√85)=5+√85
y₂=5+√85 ⇒x₂=10-(5+√85)=5-√85
Answer: the numbers are (5-√85) and (5+√85)

Answer:
Step-by-step explanation:
length=1 m
base of triangle=10 m
height=5m
volume= 1/2×10×5×1=25 m cube.
slant height l=√(5²+5²)=√50=5√2
slant surface area=2[5√2×1]=10√2
area of front and back=2×1/2(10×5)=50
total surface area=50+10√2≈50+14.14≈64.14 m²
Answer:
B) >
Step-by-step explanation:
We can convert the fractions into decimals to see which is greater.
3/5 = 0.6
5/10 = 0.5
From this, we can see that 3/5 is greater than 5/10, so the sign is >.
hope this helps :)
