Answer:
(2A)/h -a =b
Step-by-step explanation:
A= [h(a+b)]/2 I rewrote the formula, because h and a+b are in the numerator.
2A=h(a+b) Multiply both sides of equation by 2
(2A)/h= a+b Divide both side by h
(2A)/h -a= b Subtract a from both sides

The value of a is 72.74.
<h3>What is Probability ?</h3>
Probability is the study of likeliness of an event to happen.
It is given that
The mean 
of the distribution is 70
Standard deviation 
is 2
p( x<a) = 0.9147
a = ?
From Z table
For p ( p < 0.9147) , z = 1.37
a = 70+ 2*1.37
a = 72.74
Therefore the value of a is 72.74.

Triangular prisms are longer, this is a triangular pyramid
Answer: 46-3i
Step-by-step explanation: Use the FOIL method, (a+b)(c+d)=ac+ad+bc+bd. Collect like terms then simplify.
(6+7i)(3−4i)
18−24i+21i+28
(18+28)+(−24i+21i)
46-3i
