Answer:
Step-by-step explanation:
Given
Find the length of HG
First, it should be noted that the displayed figure is a trapezium
<em>The area of a trapezium is calculated by multiplying the sum of parallel sides by half its height;</em>
In this case;
Substitute the values of Area, HE and EF
Divide both sides by 4
Subtract 12 from both sides
<em>Hence, the length of HG is 5mm</em>
Answer:
36.0
Step-by-step explanation:
Answer:
n = 9
Step-by-step explanation:
Note that
256 = , thus
=
Since the bases on both sides are equal (2) equate the exponents
n - 1 = 8 ( add 1 to both sides )
n = 9
