B. 81 square units
Area for a square is length times width. In this case, both are 9 so 9 x 9 = 81
Answer:
$2.75
Step-by-step explanation:
3x+2y=7
2x+4y=8
Multiply eq1 by 2
6x+4y=14
Subtract eq1 by eq2
4x=6
x=3/2
y=5/4
1.5+1.25
2.75
Hope this helps plz mark brainliest :D
Answer:
Option (D)
Step-by-step explanation:
Subtraction property of equality tells that whatever subtracted from one side of the equation must be subtracted from the other side.
If x + 2 = 2,
By the property of subtraction of equality,
x + 2 - 2 = 2 - 2
x = 0
But in the given question,
shows the addition property of equality in step (2)
Therefore, subtraction property of equality was not applied.
Option (D) will be the answer.

Answer:
(6.5, -7.5)
Step-by-step explanation:
Use the midpoint formula (x1 + x2) / 2 , (y1 + y2) / 2
Plug in the points:
(-3 + 16) / 2 , (-5 - 10) / 2
13/2 , -15/2
6.5, -7.5
So, the coordinates of midpoint M are (6.5, -7.5)
