Answer:
The coordinates of B are (-2 , 9)
Step-by-step explanation:
A (8, 4)
M (3 , -1)
To calculate a midpoint you have to add the corresponding coordinates of each point and divide them by 2
(Ax + Bx) / 2 = Mx
(8 + Bx) / 2 = 3
8 + Bx = 3 * 2
Bx = 6 - 8
Bx = -2
(Ay + By) / 2 = My
( -1 + By) / 2 = 4
-1 + By = 4 * 2
By = 8 + 1
By = 9
The coordinates of B are (-2 , 9)
A(b-c)
First substitute values
-8(12+4)=
Next, solve using ordering of PEMDAS
-8 (12+4)=
-8 (16)=12
Correct Answer: A. 2(n+8).
First we need to do 12 ÷ 4 to see how many times that goes in. You get 3. Then you do
Answer:
18 cm²
Step-by-step explanation:
Based on the given information, the first object has an area of 12 cm² and the scale factor is 1.5. Since we know that, we can simply take the first area and multiply it by the scale factor:
12 · 1.5 = 18
Therefore, the second object will have an area of 18 cm².
