Answer:
b is the answer
Step-by-step explanation:
Answer:
h = 6 cm
Step-by-step explanation:
Atriangle = b×h/2
18cm² = 6cm×h/2
36cm² = 6cm×h
h = 36cm²/6cm
h = 6 cm
Answer:
and 
Step-by-step explanation:
Given
5 daises to 2 roses
Required
Determine the relationship between them
The question shows a direct proportion between number of daises and roses.
i.e.

Where d = daises and r = roses
Convert the above expression to an equation

Make k the subject

When d = 5 and r = 2;


So, the first relationship between d and r can be gotten by substituting 2.5 for k in d = kr
So:

----------- (1)
Make r the subject in (1)
------------------------(2)
Hence, the relationships between d and r are:
and 
4y=5x+8
5y=-2x+30
the y always goes first. then the equal sign. next is x and finally just the digit which is also known as "b".
Step-by-step explanation:
75 is equal to opposite angle of x.
so,
75° +65°+ x=180°( by all angles sum)
140°+x=180°
x=180°-140°
x=40°
