First we want to find the least common denominator of both fractions, and that would be 12.
Next we change the denominators and make them the same as the LCD 12
Next we want to join them together and make it 9 + 7 over 12
Now we want to make it 16/12 since 9 + 7 = 16 and 12 was already the denominator
Next we want to simplify the fraction 16/12 and make it 4/3.
And lastly we want to make 4/3 into a mixed fraction and we get the answer

Answer: 1 1/3

Solve 2x2 + 12x - 14 = 0 by completing the square
vovangra [49]

Answer:

<h2>x = -7 or x = 1</h2>

Step-by-step explanation:

(a+b)^2=a^2+2ab+b^2\qquad(*)\\\\\\2x^2+12x-14=0\qquad\text{divide both sides by 2}\\\\x^2+6x-7=0\qquad\text{add 7 to both sides}\\\\x^2+2(x)(3)=7\qquad\text{add}\ 3^2=9\ \text{to both sides}\\\\\underbrace{x^2+2(x)(3)+3^2}_{(*)}=7+9\\\\(x+3)^2=16\Rightarrow x+3=\pm\sqrt{16}\\\\x+3=-4\ or\ x+3=4\qquad\text{subtract 3 from both sides}\\\\x=-7\ or\ x=1

First Chart: Perimeter

Square Portion:

Original Side Lengths: P = 4  (1 + 1 + 1 + 1 ) =4

Double Side Lengths: P = 8 (2 x 4 = 8)

Triple Side Lengths: P = 12  (4 x 3 = 12)

Quadruple Side Lengths: P = 16 (4 x 4 = 16)

Rectangle Portion:

Original Side Lengths: P = 6 (1 x 2 + 2 x 2 = 6)

Double Side Lengths: P = 12 (2 x 2 + 4 x 2 = 12)

Triple Side Lengths: P = 24  (4 x 2 + 8 x 2 = 24)

Quadruple Side Lengths: P = 48 (8 x 2 + 16 x 2 = 48)

Second Chart: Area

Square Portion:

Original Side Lengths: A = 1 (1 x 1 = 1)

Double Side Lengths: A = 4 (2 x 2 = 4)

Triple Side Lengths: A = 9 (3 x 3 = 9

Quadruple Side Lengths: A = 16 ( 4 x 4 = 16)

Rectangle Portion:

Original Side Lengths: A = 2 ( 1 x 2 = 2 )

Double Side Lengths: A = 8 ( 2 x 4 = 8)

Triple Side Lengths: A = 18 ( 3 x 6 = 18)

Quadruple Side Lengths: A = 32 (4 x 8 = 32)

What is the greatest possible whole number remainder if you divide any number by 41?
OleMash [197]

The quotient remainder theorem: Given any integer A, and a positive integer B, there exist unique integers Q and R such that

A= B · Q + R where 0 ≤ R < B.

Q is called quotient and R is called remainder.

According to this theorem, when you divide any number by 41, you can obtain remainder R such that 0 ≤ R < 41. Then the greatest possible whole number remainder is 40.
