Gcf is the grouping of all the factors common to both groups
lcm is a group of all the factors that has all the elements of both groups
factor
20x^2y^3=2*2*5*x*x*y*y*y
60x^3y^2=2*2*3*5*x*x*x*y*y
40xy^2=2*2*2*5*x*y*y
the GCF=2*2*5*x*y*y=20xy^2
the LCM=2*2*2*3*5*x*x*x*y*y*y=120x^3y^3
Answer:
1. 40.00 sq units
2. 37.5 sq units
Step-by-step explanation:
1. Given slant height as 3 and the square base side as 4,
-The surface area of a right squared pyramid is calculated by summing the areas of the 4 triangles and the square base:

Hence, the area of the square pyramid is 40.00 sq units
2. The surface area of a cube is equivalent to 6 times the side of one face.
-Given the dimension of the sides as 2.5, surface area is obtained as:

Hence, the surface area of the cube is 37.5 sq units
What are all the numbers on the spinner
False
Because the left side comes out to a sum of 40 while 15-7 equals 8 and 24 times 3 equals 72 72 plus 8 equals 80 divided by 2 equals 40 and 8 times 9 equals 72 plus 6 equals 78 plus 6 equals 84
