Kay [80]

Answer:

27.2mm²

Step-by-step explanation:

Area of a triangle = \frac{1}{2} * base * height

Base of this triangle = 8mm

Height = 6.8mm

Area = \frac{1}{2} * 8mm * 6.8mm

       = 4mm * 6.8mm

       = 27.2mm²

Find xy if x + y=3, x^2 + y^2 = 5
Vesna [10]

Answer:

mark me

Step-by-step explanation:

x+y=3

x=3-y

putting the value of x

in this

x²+y²=5

(3-y) ²+y²=5

9-6y+y²+y²=5

2y²-6y+9-5=0

2y²-6y+4=0

2y²-4y-2y+4=0

2y(y-2)-2(y-2)=0

(2y-2) (y-2) =0

2y-2=0 or y-2=0

y=1 or y=2

so x=2 or 1

so x×y=2×1 or 1×2=2

I HOPE THIS WILL HELP YOU MARK ME BRAINLIEST
