K=4(5)
k=20
you just plug in 5 for d and multiply normally from there.
Just plug in a = 5, y = -3 in that!
2a + ay = 2(5) + 5(-3) = 10 -15 = -5
thats it!
Triangles ABC and DEF may or may not be congruent, because the angle-angle-angle (AAA) postulate is not a criterion for congruency of any two triangles. This is because the angle-angle-angle postulate only incorporates the angles of the triangles, and the side lengths are not specified, so congruency may or may not be true for these triangles.
The answer is d x 15 =100
In order to get the value of d, you must transpose the constant 15 to the left side of the equation.
It can also be written like this:
15d = 100
Divide both sides by 15:
15d / 15 =100/15
d = 6.667 meters per second
