Answer:

Therefore,

The Dimensions are,

Length = 34\ cm\\\\Width = 9\ cm

Step-by-step explanation:

Given:

Perimeter of a rectangle,

Perimeter = 86 cm

let "x" be the width of rectangle,

Width = x

then according to the given condition,

length will be given as,

Length = 3x+7

To Find:

Length =?

Width =?

Solution:

Perimeter of rectangle is given by,

\textrm{Perimeter of Rectangle}=2(Length+Width)

Substituting the values we get

86=2(3x+7+x)\\\\86=2(4x+7).........Equation\\\\86=8x+14\\\\8x=86-14=72\\\\x=\dfrac{72}{8}=9\ cm

Substituting "x" in Length we get

Length = 3\times 9 +7=34

Also Area Of Rectangle is given by

\textrm{Areaof Rectangle}=(Length\times Width)=34\times 9=306\ cm^{2}

Therefore,

The Dimensions are,

Length = 34\ cm\\\\Width = 9\ cm

substitute the given values into the formula & solve for the unknown variable A = bh ; A = 12 , b =4
Sauron [17]

A = bh

12 = 4 × h [substitute A for 12 and b for h]

12 / 4 = h

3 = h

Therefore, h equals 4.

How do you find the answer so confused
alexandr402 [8]
For which question, I can help,
<span>for number 9, parallel lines have the same exact slope, so divide each of them by to isolate the y and then see if the slope (number multiplied by x) is the same as the other problems . PS: focus on the slope, rest of equation doesn't matter in this question</span>

A florist has to choose four different types of flowers to include in a bouquet. In how many ways can the florist do this, if th
Nat2105 [25]

Answer:

Step-by-step explanation:

Given:

Type of Flowers = 5

To choose = 4

Required

Number of ways 4 can be chosen

The first flower can be chosen in 5 ways

The second flower can be chosen in 4 ways

The third flower can be chosen in 3 ways

The fourth flower can be chosen in 2 ways

Total Number of Selection = 5 * 4 * 3 * 2

Total Number of Selection = 120 ways;

Alternatively, this can be solved using concept of Permutation;

Given that 4 flowers to be chosen from 5,

then n = 5 and r = 4

Such that

nPr = \frac{n!}{(n - r)!}

Substitute 5 for n and 4 for r

5P4 = \frac{5!}{(5 - 4)!}

5P4 = \frac{5!}{1!}

5P4 = \frac{5*4*3*2*1}{1}

5P4 = \frac{120}{1}

5P4 = 120

Hence, the number of ways the florist can chose 4 flowers from 5 is 120 ways
