Which best explains why all equilateral triangles are similar? a. all equilateral triangles can be mapped onto each other using dilations. b. all equialeratl triangles can be mapped onto each other using rigid transformations c. all equilateral triangles can be mapped onto each other using combo of dilations and rigid transformations. d. all equilateral triangles are congruent and therefore similar, with side lengths in a 1: 1 ratio

(a) option is correct.

Step-by-step explanation:

Equilateral triangles have all the three sides of equal length and all the three angles equal to 60 degree.

Only thing which can be changed in an equilateral triangle is the length of the sides.

Moreover, dilation is a transformation used to change the size of the figure via some scale or number.

So, when dilation is applied on an equilateral triangle, its size can be made small or large as per the requirement.

Hence, equilateral triangles can be mapped onto each other using dilations.

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
