D because there are 20 objects in all and because there are 3 green cubes
Answer:
1 and 2 are not congruent; 1 and 3 are congruent; 1 and 4 are congruent; 2 and 3 are not congruent; 2 and 4 are not congruent; 3 and 4 are congruent.
Step-by-step explanation:
From the diagram, we can see that the angle measures and side measures of figures 1, 3 and 4 are the same. This means that these three figures are congruent. Figure 2, however, is not congruent to any of the other 3.
Answer:
∠2 and ∠5
Explanation:
Basically, vertical angles would be facing opposite sides but the measure of their angle is equal.
The total surface area of the cuboid is 120 cm2
1)
3x^-1y^2x^3y^-1
when base are same powers add
3x^(-1+3)y^(-1+2)
3x^2y
2)
(-3) -(2)(-4)/(-2)-(-1)
(-3)+8/-2+1
-3+8/-1
5/-1
-5
