1. it means combining like terms with rational coefficients
2. essentially using the distributive property
Answer:
Congruent triangles have both the same shape and the same size. triangles ABC and DEF are congruent; they have the same angle measures and the same side lengths.
Similar triangles have the same shape, but not necessarily the same size. In the figure below, triangles ABC and XYZ are similar, but not congruent; they have the same angle measures, but not the same side lengths.
Step-by-step explanation:
Answer:
2.72 x 10^4
Step-by-step explanation:
2.4 x 10^4
= 24000
3.2 x 10^3
= 3200
Therefore,
(2.4 x 10^4) + (3.2 x 10^3)
= 24000 + 3200
= 27200
= 2.72 x 10^4
