Triangles A and B are right-angled. 5 cm

a) Show that the two shorter sides in triangle A have the
same length as the two shorter sides in triangle B.​

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
