Answer:
scale factor is: 2.25
Step-by-step explanation:
Surface area = 56 cm2
Explanation:
Area of square base = Side x Side = 4 x 4 = 16 cm2
Area of triangle = 1/2 x Base x Height = 1/2 x 4 x 5 = 10 cm2
Area of 4 triangles = 10 x 4 = 40 cm2
Surface area of pyramid = 16 + 40 = 56 cm2
-(5 + (-11.3)) + (-4.3)
-(5 - 11.3) + (-4.3)
Distribute -1 into the parenthesis:
-5 + 11.3 + (-4.3)
-5 + 11.3 - 4.3
Add:
6.3 - 4.3
Subtract:
2
