$\text {Hello! Let's solve this Equation!}$

$\text {Your First Step is to Simplify the Equation:}$

$\text {(2x+4x)+(8+3)}$

$\text {6x+11=3x-10}$

$\text {The Next Step is to Subtract 3x:}$

$\text {6x+11-3x=3x-10-3x}\\\text {3x+11=-10}$

$\text {Next Step is to Subtract 11:}$

$\text {Q: Why Subtract 11?}$

$\text {A: So they cancel out. We cross them out once we subtract.}$

$\text {3x+11-11=-10-11}\\\text {3x=-21}$

$\text {The Final Step is to Divide 3:}$

$\text {3x/3=-21/3}$

$\text {Your Answer will be}$

$\fbox {x=-7}$

$\text {Best of Luck!}$

$\text {-LimitedX}$

Answer:

Step-by-step explanation:

1. To find the area of a semicircle the formula is

$A=\frac{\pi r^2}{2} \\=\frac{\pi 1^2}{2} \\=6.283m^2$

The square

$A=a^2=2^2=4m^2\\6.283+4=10.283m^2$

2. Triangle

$A=\frac{ab}{2} \\=\frac{6*2.5}{2} \\=7.5m^2\\7.5*2=15m^2$

Rectangle

$A=wl=8*13=104m^2$

$104-15=89m^2$

3.

Semicircle

$A=\frac{\pi r^2}{2} \\=\frac{\pi 3^2}{2} \\\\=14.137m^2$

Square

$A=a^2=6^2=36$

$36-14.137=21.863m^2$

Can someone plz help me i will thank u so much

klemol [59]

Answer:

2 hours and 29 minutes

Step-by-step explanation:

if you change 9 hours to minutes you get 540 plus 17 equals 557. if you turn 6 hours to minutes it's 360 plus 48 equals 408. 557 minus 408 equals 149 minutes. Now if you convert it to hours and minutes you need to divide by 60. So if you divide it you get 2 hours and 29 minutes. hope this helped! :)

I guess I'm lacking in differential equations. I couldn't solve this question. Can you help me?

Sonja [21]

Answer:

See Explanation.

General Formulas and Concepts:

<u>Pre-Algebra</u>

Equality Properties

Reciprocals

<u>Algebra II</u>

Log/Ln Property: $ln(\frac{a}{b} ) = ln(a) - ln(b)$

<u>Calculus</u>

Derivatives

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Chain Rule: $\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)$

Derivative of Ln: $\frac{d}{dx} [ln(u)] = \frac{u'}{u}$

Step-by-step explanation:

<u>Step 1: Define</u>

$ln(\frac{2x-1}{x-1} )=t$

<u>Step 2: Differentiate</u>

Rewrite: $t = ln(\frac{2x-1}{x-1})$
Rewrite [Ln Properties]: $t = ln(2x-1) - ln(x - 1)$
Differentiate [Ln/Chain Rule/Basic Power Rule]: $\frac{dt}{dx} = \frac{1}{2x-1} \cdot 2 - \frac{1}{x-1} \cdot 1$
Simplify: $\frac{dt}{dx} = \frac{2}{2x-1} - \frac{1}{x-1}$
Rewrite: $\frac{dt}{dx} = \frac{2(x-1)}{(2x-1)(x-1)} - \frac{2x-1}{(2x-1)(x-1)}$
Combine: $\frac{dt}{dx} = \frac{-1}{(2x-1)(x-1)}$
Reciprocate: $\frac{dx}{dt} = -(2x-1)(x-1)$
Distribute: $\frac{dx}{dt} = (1-2x)(x-1)$
