Answer:
10.5
Step-by-step explanation:
Its a right triangle, and the units were on right there, so I found the perimeter of the square it would be, then divided it by 2, because 2 triangles make a square.
brainiest?
(9+12)/2 = 10.5
10 children cuz those seven sons are siblings so they would have the same sisters
Answer:
y = x - 6
Step-by-step explanation:
the slope-intercept form for any line is y = mx + b, where m is the slope and b is the y-intercept.
now, let's calculate the slope:
1-2/7-8= -1/-1 = 1
here is the equation we currently have solved: y = x + b
now we have to solve for the y-intercept. to do this, we substitute one of the given points into the equation, and solve for b.
let's use (8, 2). in this ordered pair, the 8 is the x, and the 2 is the y.
2= 8 +b
2 -8=b
b=-6
and now we have our final equation!
y = x - 6
hope this helped! please let me know if you are confused about anything i did
The answer would most likely be B) Distributive Property as he had used it on the left side, but was incorrect as he did it to both sides.
540/5=60
60/2=30
so answer is 30
