If you have 36 ft of fencing, what are the bases and side lengths of the different parallelograms you could enclose with the fen

serious [3.7K]

Answer:

$(l,w) = (1,17)$

$(l,w) = (2,16)$

$(l,w) = (3,15)$

---

---

-

$(l,w) = (9,9)$

Step-by-step explanation:

Given

$P = 36ft$ --- perimeter

$l \to length$

$w \to width$

Required

Possible dimension of different parallelogram

The perimeter is calculated as:

$P=2(l+w)\\\\\\$

So,we have:

$2(l+w)=36$

Divide by 2

$l + w = 18$

Since l and w must be positive integers, the possible dimensions are:

$(l,w) = (1,17)$

$(l,w) = (2,16)$

$(l,w) = (3,15)$

---

---

-

$(l,w) = (9,9)$

Find the roots for the above given quadratic equation.<br><br> Please show the working too.

Mars2501 [29]

Step-by-step explanation:

$9x^{2} - 9 (a + b)x + 2a^{2} + 5ab + 2b^{2} = 0\\9x^{2} - 3[(3a + 3b)]x + 2a^{2} + 4ab +ab + 2b^{2} = 0\\9x^{2} - 3[(a + 2b) + (2a + b)]x + 2a[a + 2b] + b [a + 2b] = 0\\9x^{2} - 3(a + 2b)x - 3 (2a + b) + (a + 2b)(2a + b) = 0\\3x [3x - (a + 2b)] -(2a + b)[3x - (a + 2b)]=0\\\:\: [3x - (a + 2b)] - [3x - (2a + b)] = 0\\\\\\\\\circ\:3x - (2a + b) = 0\\\boxed{\underline{x = \frac{2a + b}{3} }}\\\\\\\\\circ\:3x - (2a + b) = 0\\\boxed{\underline{x = \frac{a + 2b}{3} }}$

So, the roots are:

<u>1) x = 2a + b/3</u>

<u>2) x = a + 2b/3</u>

Please help !<br> I need the answers for #43 and #44

Vlad [161]

43. 9 + 10 + 13 + 13 = $45

45 - 1 = 44

44 x 4 = 176

176 + 8 = 184

184/4 = 46

46 tokens per person

44. a. 22 x 5 = 110

943/110 = 8.7

you will need 9 bookcases

b. 110 x 9 = 990

990 - 943 = 47

47 - 44 = 3

There will be 3 books on the third shelf.
