Answer:
52
Step-by-step explanation:
(2×5)+(8×5)+2
10+40+2
52
( - 10, - 22 )
using the midpoint formula,
let the other endpoint have coordinates (x, y) then
(2 + x ) = - 4 ( multiply through by 2 )
2 + x = - 8 ( subtract 2 from both sides ) then
x = -8 - 2 = - 10 ← value of x-coordinate
Similarly for y-coordinate
(8 + y ) = - 7 ( multiply through by 2 )
8 + y = - 14 ( subtract 8 from both sides )
y = - 14 - 8 = - 22 ← y -coordinate
the other endpoint is ( - 10, - 22 )
2x^3+7x^2+12x-8 is the answer
Answer:
y=3/4x-4 and ignore this stuff ejdndjsienensmsk
A^2 + b^2 = c^2
9^2 + 12^2 = 225
square root of 225 is 15
