Answer:

B) 7

Step-by-step explanation:

<em>a prime number</em> is a number that is divisible by 1 and itself . (eg : 3 is a prime number)

<h3><u>prime number examples :</u></h3>

1, 3,5, 7, 11, 13, 17, 19, 23....

<h2><u>lets test it out with all of the options</u></h2>

2416 -- is divisible by 2 ..etc.. hence ----not a prime number.

2417 --- is divisible by 1 and itself --- a prime number

2418-- divisible by 2 ..etc --- not a prime number

2419--- divisible by 41 ..etc... -- not a prime number

hence 2417 is the only one that is a prime number

<h3><u>the answer is B). 7 </u></h3>

Length of a rectangle is 5 cm longer than the width. Four squares are constructed outside the rectangle such that each of the sq
stiv31 [10]

Answer:

18

Step-by-step explanation:

Remark

This is one of those questions that can throw you. The problem is that do you include the original rectangle or not. The way it is written it sounds like you shouldn't

However if you don't the question gives you 2 complex answers. (answers with the sqrt( - 1) in them.

Solution

Let the width = x

Let the length = x + 5

Area of the rectangle: L * w = x * (x + 5)

Area of the smaller squares (there are 2)

Area = 2*s^2

x = s

Area = 2 * x^2

Area of the larger squares = 2 * (x+5)^2

Total Area

x*(x + 5) + 2x^2 + 2(x + 5)^2 = 120                 Expand

x^2 + 5x + 2x^2 + 2(x^2 + 10x + 25) = 120     Remove the brackets

x^2 + 5x + 2x^2 + 2x^2 + 20x + 50 = 120      collect the like terms on the left

5x^2 + 25x +  50 = 120                                   Subtract 120 from both sides.

5x^2 + 25x - 70 = 0                                         Divide through by 5

x^2 + 5x - 14 = 0                                               Factor

(x + 7)(x - 2) = 0                                                 x + 7 has no meaning  

x - 2 =  0

x = 2                                                              

Perimeter

P = 2*w + 2*L

w = 2

L = 2 + 5

L = 7

P = 2*2 + 2 * 7

P = 4 + 14

P = 18
