The length of the rectangle is 4cm more than it's width.if the perimeter is 20cm. find the width​
oksian1 [2.3K]

Answer:

  3 cm

Step-by-step explanation:

The given relation between length and width can be used in the perimeter formula to find the width.

__

Let w represent the width of the rectangle in centimeters. The length is 4 cm more, so can be represented by (w+4). Using these values and the given perimeter in the perimeter formula, we find ...

  P = 2(L +W) . . . . . perimeter formula

  20 = 2((w +4) +w) . . . . known values substituted

  10 = 2w +4 . . . . . . . . divide by 2, collect terms

  6 = 2w . . . . . . . . . subtract 4

  3 = w . . . . . . . . divide by 2

The width of the rectangle is 3 cm.

__

<em>Additional comment</em>

The length is 7 cm.

Cos(8x+21)=sin(-2x+51) Find the two angles represented in degrees ??? Someone help its 1am I can't do this
wolverine [178]

Answer:

45 and 135degrees

Step-by-step explanation:

Cos(8x+21)=sin(-2x+51) Find the two angles represented in degrees ??? Someone help its 1am I can't do this

In trigonometry, cosx = sin(90-x)

Hence:

Cos(8x+21) = sin(90-(8x+21))

Cos(8x+21) = sin(90-8x-21)

Cos(8x+21) = sin(-8x+69)

Substituting into the expression given, :

sin(-8x+69) = sin(-2x+51)

-8x+69 = -2x+51

-8x+2x = 51-69.

-6x = -18.

X = 18/6

X = 3

Since the angles 8x+21

Angle = 8(3)+21

Angle = 45

The angles represented in degrees are 45 and (180-45) = 135degrees

If k = (n + 2)(n – 2), where n is an integer greater than 2, what is the value of k ? (1) k is the product of two primes. (2) k
Korolek [52]

Answer:

The answer is k=77

Step-by-step explanation:

It is given that n is an integer and greater than 2. Let us simplify k = (n + 2)(n – 2) to k=n^2-4.

In (1) it is stated that k is the product of two primes and in (2) it is stated that k<100. To solve the question we need to consider both cases (1) and (2).

Let say n=9 then k=n^2-4 becomes k=81-4=77. Well, 77 is the product of two prime numbers 7 and 11 (77=7*11). The answer is k=77
