A) Find the area of triangles in which (i) base = 8 cm, height = 5.5 cm
(ii) base = 12 cm, height = 8.4 cm​

Step-by-step explanation:

1) B=8cm                          H=5.5

A=1/2xbxh

A=I/2 x 8 x 5.5

A=22

The area of the first traingle is 22cm

2)

B=12cm                                 h=8.4

A=1/2xbxh

A=1/2 x 12 x 8.4

A=50.4

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
