Simplify 5+2i/6+i
nlexa [21]

Given problem is \frac{(5+2i)}{(6+i)}

To simplify that we need to multiply and divide by conjugate of the denominator

conjugate of denominator 6+i will be 6-i as we just need to change sign of the imaginary part

Now multiply and divide by 6-i


=\frac{(5+2i)}{(6+i)}\cdot\frac{(6-i)}{(6-i)}

=\frac{30-5i+12i-2i^2}{36-6i+6i-i^2}

=\frac{30+7i-2i^2}{36-i^2}

=\frac{30+7i-2\left(-1\right)}{36-\left(-1\right)}

=\frac{30+7i+2}{36+1}

=\frac{32+7i}{37}

=\frac{32}{37}+\frac{7}{37}i

Hence final answer is \frac{32}{37}+\frac{7}{37}i

PLEASE ANSWER QUICKLY AND HELP ME!! THANK YOU SO MUCH!!

Hello there!

To start off this problem, let's replace f(x) with x in the equation. This gives us the following.

x= \dfrac{3}{4} x+12

Subtract 3/4*x from both sides.

x- \dfrac{3}{4} x=12

\dfrac{4}{4} x-\dfrac{3}{4}x=12

\dfrac{1}{4} x=12

Now, multiply both sides by 4 to eliminate the fraction on the left side.

x=12*4=48

Your answer is B. Hope this helps! :)

Answer:

a) A = 64(2s - 1)

b) A = 1,856 cm²

Step-by-step explanation:

Given the side of the frame, 8s, and that the border that frames the picture is 4 on either side = 8:

<h3>a) Find an expression for the area of the frame, in factored form. </h3>

A = area of the square frame

A₁ = Total area (including the picture inside the frame) = (8s)²

A₂ = Area of the picture inside the frame = 4 + 4 = (8s - 8)²

To find the area of the frame, subtract the area of the picture from the total area.

A = A₁ - A₂

A = (8s)² - (8s - 8)²

Perform the necessary exponential operations:

A = 64s²- (64s² - 64s - 64s + 64)

A = 64s²- (64s² - 128s + 64)

A = 64s²- (64s² - 128s + 64)

Distribute -1 into the parenthesis:

A = 64s²- 64s² + 128s - 64

Combine like terms:

A = 0 + 128s - 64

A = 128s - 64

Factor out 64:

A = 64(2s - 1)

The expression for the area of the frame in factored form is: A = 64(2s - 1).

<h3>b) Determine the area of the frame when s = 15cm</h3>

Using the same expression from part A:

A = 64(2s - 1)

Substitute s = 15 into the expression:

A = 64[2(15) - 1]

A = 64(30 - 1)

A = 64(29)

A = 1,856 cm²

Therefore, the area of the frame that has a side of 15 cm is: A = 1,856 cm²
