Step-by-step explanation:
The midpoint can be found with the formula.
midpoint = (x1+x2) /2 , (y1 + y2 )/2
( x1 , y1), and (x2 , y2 ) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.
P = (0,0)
midpoint = (2,5)
x midpoint = 2 = (0+ x2)/2
×2 = 4
y midpoint = 5 = (y2+0 )/2
10 = y2
so the point Q is (4 , 10)
She would have to work 13 hours
DB is a median (given). It goes from vertex point D to midpoint B.
The point B is the midpoint of segment AC. So B cuts AC into two equal halves: AB and AC
Meaning AB = AC
AC = AB+BC ... segment addition postulate
AC = AB+AB ... substitution; replace BC with AB (valid because AB = AC)
AC = 2*AB
2*AB = AC
2*AB = 50 ... substitution; replace AC with 50
2*AB/2 = 50/2 ... divide both sides by 2
AB = 25 which is the answer

hope it helps you
make me brainliest plz
Correct option is C) A² - B² + BA – AB
Step-by-step explanation:
(A+B)(A−B)=A(A−B)+B(A−B).........because matrix product is distributive.
=A² + BA - AB - B²
And as matrix product is not commutative, so AB¦=¦BA
Hence option C is correct.
