Well,you can use the pythagorean theorem,which is a^2+b^2=c^2 to solve for x.

$x+31$ and $2x-59$ are congruent sides

So we have
$2x-59=x+31$
⇒ $x-59=31$
⇒ $x=90$

Plug in:
$x+31=90+31=121$
$2x-59=2(90)-59=180-59=121$
$x-7=90-7=83$

3(-10n + 9) - 3(1 + 8n)= 24

Arlecino [84]

Answer:

n=0

Step-by-step explanation:

Let's solve your equation step-by-step.

3(−10n+9)−3(1+8n)=24

Step 1: Simplify both sides of the equation.

3(−10n+9)−3(1+8n)=24

(3)(−10n)+(3)(9)+(−3)(1)+(−3)(8n)=24(Distribute)

−30n+27+−3+−24n=24

(−30n+−24n)+(27+−3)=24(Combine Like Terms)

−54n+24=24

Step 2: Subtract 24 from both sides.

−54n+24−24=24−24

−54n=0

Step 3: Divide both sides by -54.

−54n/-54=0/−54

Permutations and combination question ^^

mario62 [17]

Answer: 22) A

Step-by-step explanation:

First, order doesn't matter so it is a Combination.

In other words, it doesn't matter which person was chosen 1st, 2nd, 3rd, or 4th to bring food because they are all bringing "food".

Next, If you are going to choose person to 4 people to bring food out of a total of 4 + 3 + 1 = 8 people, you get → ₈C₄

And you are going to choose 3 people to bring decorations out the remaining 8 - 4 = 4 people, you get → ₄C₃

And you are going to choose 1 person to be the host out of the remaining 4 - 3 = 1 person, you get → ₁C₁

"And" means multiplication so altogether you get ⇒ ₈C₄ × ₄C₃ × ₁C₁
