Mathematics
1 answer:
Art [367]3 years ago
8 0

Answer:

f = 6, g = 8.

Step-by-step explanation:

The area of ABCD = f * g so

fg = 48.

The area of the trapezium ABCE

= 1/2 * (g + g + 4) * f = 60

f/2 ( 2g + 4) = 60

fg + 2f = 60

But fg = 48, so

48 + 2f = 60

2f = 12

f = 6

and therefore g = 48/f = 48/6

= 8 .

U(8, 9) and V(2, 5) are the endpoints of a line segment. What is the midpoint M of that line segment?
Crazy boy [7]

Answer:

(5, 7 )

Step-by-step explanation:

Given 2 points (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

here (x₁, y₁ ) = U(8, 9) and (x₂, y₂ ) = V(2, 5), thus

midpoint = [0.5(8 + 2), 0.5(9 + 5) ] = [0.5(10), 0.5(14) ] = (5, 7 )
