Answer:
17
Step-by-step explanation:
Becasue a di has 6 sides so you would just divide 642 by 6
we are given

we can see that
each terms are multiple of 2
so, we can factor out 2

we can divide both sides by 2

we can rearrange it

now, we can move 10 on right side


now, we can add both sides 7^2 and 5^2


we can simplify it

we can also write as

The equivalent equation is;

Step-by-step explanation:
Given that the area of a trapezoid is ;
A=1/2 (b₁+b₂)h
When the equation is solved for b₁ it will be;
A=1/2 (b₁+b₂)h
This can be written as;
A=h/2 (b₁+b₂)
Multiply both sides by 2/h
2A/h = b₁+b₂
Make b₁ subject of the formula
2A/h - b₂ = b₁
