IF ANYONE CAN ANSWER THIS CORRECTLY I WILL GIVE THEM BRAINLIEST. 8 - i

3-2i

If the expression above is rewritten in the form a+bi, where a and b are real numbers, what is the value of a? (Note: i=√−1)

Re(8−i3−2i)=Re(2+i)= 2

Step-by-step explanation:

So you are asking for  Re(8−i3−2i)

First problem is, we haven’t got something which looks like a+bi here, so we have to simplify (8-i)/(3–2i).

Multiply numerator and denominator by the conjugate of the latter:

8−i3−2i=(8−i)(3+2i)13

Simplify:

=26+13i13=2+i

So  Re(8−i3−2i)=Re(2+i)= 2

So you are asking for  Re(8−i3−2i)

First problem is, we haven’t got something which looks like a+bi here, so we have to simplify (8-i)/(3–2i).

Multiply numerator and denominator by the conjugate of the latter:

8−i3−2i=(8−i)(3+2i)13

Simplify:

=26+13i13=2+i

So  Re(8−i3−2i)=Re(2+i)= 2

Step-by-step explanation:

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
