Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper. The per

imeter of the rectangle is 2(5x – 2) + 2(3x + 1). If x = 4 centimeters, what is the total distance Zohar needs to cut with the scissors? 31 centimeters 36 centimeters 62 centimeters 70 centimeters

They give you the equation: 2(5x-2)+2(3x+1)

and they give you x. x=4

just substitute and solve: 2((5•4)-2)+2((3•4)+1)=2(20-2)+2(12+1)=2(18)+2(13)=36+26=62

There are 4 pizzas which each have 12 slices. These pizzas will be divided between 15 people. How many slices does each person g
jasenka [17]
<h2><u>Anѕwєr :</u></h2>

48/15 or 3 whole 3/15

<h2><u>Explαnαtion :</u></h2>

There are 4 pizzas and each have 12 slices. So,

→ Number of slices each pizza have = 12 slices

→ Number of slices 12 pizzas have = (12 × 4) slices

→ Number of slices 12 pizzas have = 48 slices

Now, we have to find the number of slices each person get if they are split evenly.

→ Number of people = 15

Let the the number of slices each person get if they are split evenly be x. So,

→ Total number of slices = Number of people × Number of slices each gets

→ 48 = 15x

→ <u>48/15 or 3 whole 3/15 = Number of slices each gets</u>

Therefore, the number of slices each person get if they are split evenly is 48/15.

A rectangle has an area of 48
nika2105 [10]
Answer: i didnt understand the answer choice but the correct answer is 48/12=width. width=4

Step-by-step explanation:
as we know the area of a rectangle is area=length X width
so we plug in 48 as area and 12 as length

48=12 x width
48/12=width(divide both sides by 12)

Determine all critical points the the function:
romanna [79]
\bf y=x^2-32\sqrt{x}\implies \cfrac{dy}{dx}=2x-32\cdot \cfrac{1}{2}x^{-\frac{1}{2}}\implies \cfrac{dy}{dx}=2x-\cfrac{32}{2\sqrt{x}}&#10;\\\\\\&#10;\cfrac{dy}{dx}=2x-\cfrac{16}{\sqrt{x}}\implies \cfrac{dy}{dx}=\cfrac{2\sqrt{x^3}-16}{\sqrt{x}}\\\\&#10;-----------------------------\\\\

\bf 0=\cfrac{2\sqrt{x^3}-16}{\sqrt{x}}\implies 0=2\sqrt{x^3}-16\implies 16=2\sqrt{x^3}&#10;\\\\\\&#10;8=\sqrt{x^3}\implies 2^3=\sqrt{x^3}\implies (2^3)^2=x^3\implies (2^6)^{\frac{1}{3}}=x&#10;\\\\\\&#10;2^{\frac{2}{1}}=x\implies \boxed{4=x}\\\\&#10;-----------------------------\\\\&#10;\textit{the other critical point at }\sqrt{x}=0\implies \boxed{x=0}

Two cars left the city for a suburb, 480 km away, at the same time. The speed of one of the cars was 20 km/hour greater than the
mario62 [17]

Time taken by car A = 6 hr and time taken by car B is 8 hours

<u>Explanation:</u>

<u />

Given:

Distance, d = 480 km

Let x be the time taken by B to reach the destination:

So,

Time taken by car A to reach the destination = x -2

We know:

Distance = speed X time

speed = \frac{distance}{time}

On substituting the value we get:

Speed of car A = \frac{480}{x - 2}

Speed of car B = \frac{480}{x}

Since car A travelled 20 km/hr faster than the car B, the equation becomes:

\frac{480}{x-2} = \frac{480}{x} + 20

Multiplying both sides by (x - 2) we get:

480 = \frac{480(x-2)}{x}+ 20(x-2)\\ \\480 = \frac{480x - 960}{x} + 20x - 40\\\\480 = \frac{480x - 960 + 20x^2 - 40x}{x} \\\\480x = 20x^2 + 440x - 960\\\\20x^2 - 40x - 960 = 0\\\\x^2 - 2x - 48 = 0\\\\x = 8

Therefore, time taken by car A = x - 2

                                                   = 8 - 2 hr

                                                   = 6 hr

Time taken by car B = 8 hr
