Answer: Arithmetic Sequence
Step-by-step explanation:
An Arithmetic Sequence is a sequence where each term increases by adding/subtracting some constant k. This is in contrast to a geometric sequence where each term increases by dividing/multiplying some constant k.
Answer:
The number of solutions is one
Step-by-step explanation:
Here, we want to get the number of solutions
since the linear equations are not the same, neither do they have the same x-variable, we can have only one solution
Answer:
1.Many pairs of triangles designed into a building, for example as roof ends, would be congruent, so the roof beam and the top edges of the walls are horizontal.
2.The congruent triangle is used in most of the building that are design to stay in bad conditions and Strong winds for Example the Sydney Bridge.
3.in real life two triangles are rarely exactly congruent. However they are crucial in the construction of large man-made structures. This is because a triangle is the most stable shape and the congruence is needed to create even surfaces.
Given:
Rectangular room is 10 feet; and
1 x 1 ft tiles
The expression for this problem would be:
If we know that the width is w, while the length is w + 10,
therefore the perimeter is 2w + 2 (w + 10), so you need 4w + 20 - 4, or 4w + 16
tiles. Since you do not want to count the corners, twice.
