HELP ASAP I NEED IT!!
nevsk [136]

Answer:

The two complex numbers that make the equation true are 1 + i  and 3 + 2i

(1 + i) + (3 + 2i) = 4 + 3i

Step-by-step explanation:

(1 + i) + (3 + 2i)

Combine the real and imaginary parts in numbers 1 + i and 3 + 2i

1 + 3 + (1 + 2)i

Add 1 to 3. Add 1 to 2.

4 + 3i

The two complex numbers that make the equation true are 1 + i  and 3 + 2i

The shelf is 4 feet wide and 2/3 feet deep. what is the area of the shelf?
steposvetlana [31]

Answer:

Area of the self will be =4\times \frac{2}{3}=\frac{8}{3}=2.666ft^2

Step-by-step explanation:

We have given that self is 4 feet wide and \frac{2}{3} feet deep

So length pf the shelf l = \frac{2}{3} feet

And width = 4 feet

We have to find the area of the self

We know that area is given by

Area = length × width

So area of the self will be =4\times \frac{2}{3}=\frac{8}{3}=2.666ft^2

What is the following quotient?
almond37 [142]

Answer:

B)  \sqrt{30}  - 3 \sqrt{2}  +  \sqrt{55}  -  \sqrt{33}  \div 2

Step-by-step explanation:

Step 1: First we have to get rid off the roots in the denominator.

To do that, we have to multiply the numerator and the denominator by the conjugate of √5 + √3.

The conjugate of √5 + √3 is √5 - √3.

Now multiply given expression with √5 - √3

(√6 + √11)     (√5 - √3)

------------- x   -----------

(√5 + √3)        (√5 - √3)

Step 2: Multiply the numerators and the denominators.

√6√5 - √6√3 +√11√5 -√11√3

------------------------------------------

(√5)^2 - (√3)^2

Now let's simplify to get the answer.

√30-√18 +√55 - √33

-----------------------------

5 - 3

= √30 -3√2 +√55                                     [√18 = √9√2 = 3√2]

--------------------------

2      

The answer is  \sqrt{30}  - 3 \sqrt{2}  +  \sqrt{55}  -  \sqrt{33}  \div 2


Thank you.
