do you need to include the wiggle infront of the first bracket? if not;

(x+1) ÷ [(x^2+2) x (2x-3dx)]

x^2 x 2x = 2x^3

x^2 x -3dx = -3dx^3

2 x 2x = 4x

2 x -3dx = - 6dx

i cant find a way to make it equal 0 so i think the answer is just

x+1 over 2x^3 - 3dx^3 + 4x - 6dx as a fraction

5x + 3y = 16 <br> 3x -5y = -4<br> How do I solve this

lawyer [7]

Answer:

$(2, 2)$

Step-by-step explanation:

We can solve this system of equations using the elimination method.

Let's start by multiplying the first equation by 3:

$3(5x+3y)=3(16)\\3(5x)+3(3y)=48\\15x+9y=48$

Now, multiply the second equation by 5:

$5(3x-5y)=5(-4)\\5(3x)-5(5y)=-20\\15x-25y=-20$

Since both equations have 15x, we can eliminate the x by subtracting the two equations.

$15x-15x+9y-(-25y)=48-(-20)\\9y+25y=68\\34y=68\\\text{Divide both sides by 34}\\y=2$

Now, substitute 2 for y to solve for x:

$5x+3y=16\\5x+3(2)=16\\5x+6=16\\\text{Subtract 6 from both sides}\\5x=10\\\text{Divide both sides by 2}\\x=2$

Therefore the solution to this system of equations is:

$(x, y)=(2, 2)$

Mary walks from comer D to comer E to comer F on a city block that measures 264 feet wide and 900 feet long. Kate walks

Y_Kistochka [10]

Answer:

Difference between the distances traveled by Mary and Kate = 226 feet

Step-by-step explanation:

By applying Pythagoras theorem in right ΔDEF,

(DE)² + (EF)² = (DF)²

By substituting DE = 264 feet and EF = 900 feet

(264)² + (900)² = (DF)²

DF = √(69696+810000)

= √879696

= 937.92

Distance traveled by Kate diagonally = 938 feet

Distance traveled by Mary = DE + EF

= 264 + 900

= 1164 feet

Difference between the distances traveled by Mary and Kate = DF - (DE + EF)

= 1164 - 937.92

= 226.07

≈ 226 feet
