7. The diagram shows a trapezium.
B
Diagram NOT
accurately drawn
D
AD = x cm, BC is the same length as AD. AB is twice the length of AD. DC is 4 cm
longer than AB. The perimeter of the trapezium is 38 cm.
Work out the length of AD.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

the answer will be b x² +x-1
