Answer:  \\The\: width\: is \: 6 \:  {in}^{2}  \\ \\  Step\: by\: step\: explanation: \\ Let \:  x  \: be \:  the  \: width  \: of  \: the \:  rectangle,\: x > 0\Rightarrow the \: length:2x + 8 \\ We  \: have  \: an \:  equation:x(2x + 8) = 120 \\ \Leftrightarrow 2 {x}^{2}  + 8x  + 8= 128 \\ \Leftrightarrow  {x}^{2}  + 4x   + 4 = 64 \\ \Leftrightarrow {(x + 2)}^{2}  = 64 \\ \Leftrightarrow x + 2 =  \pm8 \\ \Leftrightarrow x = 6 \:  \vee \: x =  - 10 \\ \Rightarrow x = 6 \: (x > 0)

Jerry climbed 210 feet in elevation. he want down 300 feet. what integer represents his toal changes in elevation.
babymother [125]

For every action you want to record the "Distance", you do not want to find the displacement. 210 feet + 300 feet = 510 feet. His total distance traveled is 510 feet

Displacement however would be -90 = 210 - 300 because he is now -90 feet from where he begun. The reason the 90 is negative is because he is lower now than he was before because the downward movement was greater than the upward movement.

Someone please explain this it’s confusing me.
Nesterboy [21]

Answer:

x = 4 radical 3 / 3

Step-by-step explanation:

this is a 30-60-90 triangle

the side across from the angle 30 is L

the side across from the angle 60 is L√3

the side across from the angle 90 is 2L

we are given the side across from 60⁰ so we know that:

2 = L√3

we want to solve for L, so we must divide both sides by √3 (radical three)

2/√3 = L√3/√3

you would get 2/ √3 = L, because the radical three cancels out on the L side.

but you can't have a radical in the denominator, so you have to multiply 2/√3 by radical 3

2 times √3 and √3 times √3

you get 2√3/√9

radical nine can simplify

2radical3/3 or 2√3/3

we found L, but that would equal the thirty degree angle, not the 90, 90 = 2L

multiply the number infront of the radical by two and get

4√3/3

x=4 radical 3 divided by 3

Pleaseee i need some help on these 3 questions
Zepler [3.9K]

Answer:

a) the product is equal to 953.

b) the product is greater than 443.

c) the product is greater than 181.

Step-by-step explanation:

a) 953 × 63/63 = 953

Therefore, the product is equal to 953.

b) 443 × 86/79 = 482.25

Therefore, the product is greater than 443.

c) 181 × 30/28 = 193.93

Therefore, the product is greater than 181.

Hope this helps =)

Tell how you know when you have found the prime factorization of a number
sweet-ann [11.9K]
When you end up with prime numbers for example
If you factored out 12 you could say 3x4. Now 3 is a prime number so it cant be broken down any more. You can break down 4 into 2x2. 2 is a prime number so cant be broken down any further. When 12 is factored out it is 2x2x3
