Answer:

  • \boxed{\sf{96x-70}}}

Step-by-step explanation:

Use the distributive property.

<h3>What is a distributive property?</h3>

Distributive property is a serving to distribute or allot or disperse.

<u>Distributive property:</u>

A(B+C)=AB+AC

A(B-C)=AB-AC

-10(1-9x)+6(x-10)

<u>Expand.</u>

-10(1-9x)

-10*1=-10

-10*9x=90x

\longrightarrow \sf{=-10+90x+6\left(x-10\right)}}

6(x-10)

6*x=6x

6*10=60

6x-60

<u>Rewrite the problem down.</u>

= -10+90x+6x-60

<u>Combine like terms.</u>

90x+6x-10-60

<u>Add the numbers from left to right.</u>

90x+6x=96x

96x-10-60

<u>Finally, subtract the numbers from left to right.</u>

-10-60=-70

\Longrightarrow \boxed{\sf{96x-70}}

Therefore, the final answer is<u> 96x-70.</u>

I hope this helps, let me know if you have any questions.

Find the area of the surface. The part of the surface z = xy that lies within the cylinder x2 + y2 = 36.
rewona [7]

Answer:

Step-by-step explanation:

From the given information:

The domain D of integration in polar coordinates can be represented by:

D = {(r,θ)| 0 ≤ r ≤ 6, 0 ≤ θ ≤ 2π) &;

The partial derivates for z = xy can be expressed  as:

y =\dfrac{\partial z}{\partial x} , x = \dfrac{\partial z}{\partial y}

Thus, the area of the surface is as follows:

\iint_D \sqrt{(\dfrac{\partial z}{\partial x})^2+ (\dfrac{\partial z}{\partial y})^2 +1 }\ dA = \iint_D \sqrt{(y)^2+(x)^2+1 } \ dA

= \iint_D \sqrt{x^2 +y^2 +1 } \ dA

= \int^{2 \pi}_{0} \int^{6}_{0} \ r  \sqrt{r^2 +1 } \ dr \ d \theta

=2 \pi \int^{6}_{0} \ r  \sqrt{r^2 +1 } \ dr

= 2 \pi \begin {bmatrix} \dfrac{1}{3}(r^2 +1) ^{^\dfrac{3}{2}} \end {bmatrix}^6_0

= 2 \pi \times \dfrac{1}{3}  \Bigg [ (37)^{3/2} - 1 \Bigg]

= \dfrac{2 \pi}{3} \Bigg [37 \sqrt{37} -1 \Bigg ]

Solve the following expression when<br> t = 3 and s = 2<br> (12t) = (6s)<br> Enter
larisa86 [58]

From the solution of the expression, it can be seen that s = 6 when t = 3 while t = 1 when s = 2.

<h3>How do we solve a mathematical expression?</h3>

Given:

(12t) = (6s) ........................ (1)

When t = 3, we can solve for s from the expression in equation (1) by substituting t = 3 into the equation as follows:

12 * 3 = 6s

36 = 6s

s = 36 / 6

s = 6

When s = 2, we can solve for t from the expression in equation (1) by substituting s = 2 into the equation as follows:

12t = 6 * 2

12t = 12

t = 12 / 12

t = 1
