Answer:
The ages of the children are 6, 9 and 12.
Explanation:
Let x= the age of the youngest child.
If the oldest child is twice the age of the youngest, the age of the oldest child is twice x or 2x.
If the middle child is 3 years older than the youngest, the age of the middle child is x+3.
If the sum of their ages is 27, then
x+2x+x+3=27aaa(Combine like terms)
4x+3=27aaa
aa−3a−3aaa(Subtract 3 from both sides)
4x=24
4x4=24aaa(Divide both sides by 4)
The shapes below that have a constant cross-section between a pair of faces are cylinder, cube, sphere, hexagonal, and prism.
<h3>What is the definition of geometry?</h3>
It is concerned with the geometry, region, and density of various 2D and 3D shapes.
A cylinder is a closed solid with two parallel circular bases and a curving surface connecting them.
The shapes have a constant cross-section between a pair of faces like a cylinder.
Hence,cylinder, cube, sphere, hexagonal, and prism are the forms below that have a constant cross-section between a pair of faces.
