Can someone help me please I need both area and perimeter

A=2300

P=240

Step-by-step explanation:

Area)

separate the shapes

Rectangle 1

30+20=50

50×30=1500

Rectangle 2

70-30=40

40×20=800

Area 1500+800=2300

Perimeter)

First we find every dimention

So now we add

30+30+50+70+20+40

30+30=60

60+50=110

110+70=180

180+20=200

200+40=240

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
