The area ( A) of a trapezoid can be determined by using the following formula. A=h(b1+b2)2
Where h = the height, b 1 = the length of one base, and b 2 = the length of the other base of the trapezoid, what is the result of solving this equation for h?

h=2A−(b1+b2)

h=A+2−(b1+b2)

h=A+2(b1+b2)

h=2A(b1+b2)

i really dont know

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
