Is it 7.1 or something I don’t know for sure
Answer: -2
Step-by-step explanation:
Answer:
A' ( -12 , -12 )
B' ( 6 , -3 )
C' ( 3 , 3 )
Step-by-step explanation:
To find the coordinates of a point after a dilation simply multiply the x and y values of the points by the scale factor
Points: A(-8,-8) B(4,-2) C(2,2)
Scale factor: 1.5
Coordinates after the dilation
A' = (-8,-8) --------> (-8 * 1.5 , -8 * 1.5 ) ------------> (-12 , -12)
B' = (4,-2) ---------> (4 * 1.5 , -2 * 1.5) -----------> (6 , -3 )
C' = (2 , 2) ----------> (2 * 1.5 , 2 * 1.5) -----------> (3, 3)
So inclusion the coordinates of ABC after a dilation centered at the origin with a scale factor of 1.5 are A' ( -12 , -12 ) B' ( 6 , -3 ) C' ( 3 , 3 )
Answer:
57 cm²
Step-by-step explanation:
Surface area of the yellow prism = front + back + right + left + top
✔️Area of the front = L * W
L = 4 cm
W = 3 cm
Area of the front = 4*3 = 12 cm²
✔️Area of the back = L * W
L = 4 cm
W = 3 cm
Area of the back = 4*3 = 12 cm²
✔️Area of the right face = L * W
L = 4 cm
W = 3 cm
Area of the right face = 4*3 = 12 cm²
✔️Area of the left face = L * W
L = 4 cm
W = 3 cm
Area of the left face = 4*3 = 12 cm²
✔️Area of the top = L * W
L = 3 cm
W = 3 cm
Area of the top = 3*3 = 9 cm²
✅Total = 12 + 12 + 12 + 12 + 9 = 57 cm²
