14 = 2 x 7

20 = 2² x 5

15 = 3 x 5

LCM = 2² x 3 x 5 x 7 = 420

Answer: LCM = 420

A^3+a+a^2+1 2a^2+2ab+ab^2+b^3
Vikentia [17]
\frac{a^3+a+a^2+1}{a^3+a^2+ab^2+b^2} \cdot  \frac{2a^2+2ab+ab^2+b^3}{a^3+a+a^2b+b} =\frac{a(a^2+1)+1(a^2+1)}{a^2(a+1)+b^2(a+1)} \cdot  \frac{2a(a+b)+b^2(a+b)}{a(a^2+1)+b(a^2+1)} =\\\\=\frac{(a^2+1)(a+1)}{(a+1)(a^2+b^2)} \cdot  \frac{(a+b)(2a+b^2)}{(a^2+1)(a+b)} = \frac{2a+b^2}{a^2+b^2}

At the neighborhood grocery, 4.5 pounds of chicken breast cost $53.28. Benjamin
otez555 [7]
If my math is correct this should be a simple equation. First you’d start off by figuring out how much money chicken costs per one pound.
53.28 / 4.5 = $11.84 per pound
Now take how much money the chicken costs per pound and divide it by how much Benjamin spent.
59.20 / 11.84 = 5 pounds
Your answer should be exactly 5 pounds
I apologize if this is incorrect math, but the equation seems simple at first glance.

HELP ME WITH 16 & 17
damaskus [11]

__Data__

The equilateral's lengths are all the same

Also if AB = AD = BD = CD that would mean all those sides have the exact same length

Answers and Explanations

15A. BCD has 2 acute angles and one obtuse angle, so this is an Obtuse Triangle

15B. If beforementioned = 5 cm

Then the perimeter is 5cm x 3 = 15cm

15C. ABC is a Right Triangle  

16. abcdef. Measure the angles using a protractor

17. The shortest side of ABC is AB which is 5cm, the longest is AC which is 10cm

Shortest side: Longest side

5cm:10cm

1:2 is the ratio

Qaudriladrial ABCD had cordinates A (3, 5) B(5, 2) C(8, 4) D(6, 7) qaudriladrial ABCD is a what?
Lorico [155]

The quadrilateral is a square

<h3>What are quadrilaterals?</h3>

Quadrilaterals are polygons, that have four sides and four corners

The coordinates are given as:

  • A = (3, 5)
  • B = (5, 2)
  • C = (8, 4)
  • D = (6, 7)

Start by calculating the adjacent side lengths using:

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

So, we have:

AB = \sqrt{(3- 5)^2 + (5- 2)^2}

AB = \sqrt{13}

BC = \sqrt{(8- 5)^2 + (4- 2)^2}

BC = \sqrt{13}

The side lengths are equal.

Hence, the quadrilateral is a square
