Perimeter can be found by the formula : Perimeter =  2L + 2 W

Perimeter =  2L + 2 W

Perimeter = 2(2a) + 2(a + 1) .   ← Option 4

Perimeter = 4a + 2a + 2

Perimeterr = 6a + 2                  ← Option 5

Perimeter can also be found by simply adding up all the 4 sides:
Perimeter = L + W + L + W

Perimeter = L + W + L + W

Perimeter = 2a + a + 1 + 2a + a + 1   ← Option 3

Perimeter = 3a + 1 + 3a + 1                ← Option 1


Answer: Option 1, 3, 4 and 5 are correct.

Write the equation of a line in slope intercept form given;<br> (6,-3), (0, 5)
olganol [36]

Answer:

y=(-4/3)x+5

Step-by-step explanation:

so you want to start by using y=mx+b

step one: find the slope (remember m is the slope in this)

m= \frac{y2-y1}{x2-x1}

m= \frac{5+3}{0-6}

m= \frac{8}{-6}

m= - \frac{4}{3\\}

step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.

y=mx+b

5= -4/3(0)+b

5=b

step three: rewrite y=mx+b with the values we found for m and for b

y=(-4/3)x+5

Solve to find the answer of blue pills Mr body took: number of blue pills, b, mr mattics give him was 3 more than the number of
barxatty [35]

Answer:

Mr body took 9 blue pills

Step-by-step explanation:

Total number of pills consumed = 17

Number of blue pills, b = 11

Number of blue pills, b = g + 3

So that,

b = g + 3

11 = g + 3

g = 8

Total number of pills recommended = b + g

                                                            = 11 + 8

                                                            = 19

Total number of pills consumed = 17

Thus,

Number of blue pills consumed = 17 - 8

                                                     = 9

Therefore, Mr body took 9 blue pills.

two pages that are back to back in a text have 201as the sum of their page numbers what are the page numbers.​
REY [17]

Answer:

Pages 100 and 101

Step-by-step explanation:

Round 201 to 200 (to make it easier).

Divide 200 by 2, because it is 2 pages.

You are left with 100.

100 is one of the pages, but because you rounded down 1 number, the other number must be 101, because the pages are back to back.

I hope this made sense, this is just how I figured it out. :)

A rectangular field is fully enclosed with 218 meters of fencing. The length of the field is
mestny [16]

The length and width of a rectangular field fully enclosed with 218 metes fencing  are 63 meters and 46 meters respectively.

The perimeter of a rectangle is the sum of the whole four sides. Therefore, the perimeter of a rectangle is defined as follows:

  • perimeter = 2(l + w)

where

l = length

w = width

perimeter = 218 meters

The length of the field is  17 meters longer than the width, w. Therefore, the length is defined as follows:

  • l = 17 + w

The length and the width can be calculated as follows:

218 = 2(l + w)

218 = 2(17 + w + w)

218 = 34 + 4w

218 - 34 = 4w

184 = 4w

divide both sides by 4

w = 184 / 4

w = 46 meters

length = 17 + 46

length = 63 meters
