Answer:
Height = 3.5cm.
Step-by-step explanation:
Area of a trapezium:
a+b/2 × h
Area = 14.7cm²
Parallel sides (a and b) = 5.3cm, 3.1cm
14.7cm² = 5.3 + 3.1/2 × h
h = 14.7 ÷ 4.2
h = 3.5cm
The height is 3.5cm.
Answer:
-8
Step-by-step explanation:
Given that,
n = -3
r = -8
Now we have to find the value of the given expression.
For that, you have to replace n and r with ( -3 ) and ( -8 ) respectively.
Let us solve now.
−5 + 3 ( −2r + 4n )
-5 + 3 ( -2 × -8 + 4 × -3 )
-2 ( 16 - 12 )
-2 × 4
-8
Let me know if you've any other questions. :-)
