Answer:

Step-by-step explanation:

These are geometric means problems. In the top one, a is the geometric mean as the height for both the smaller triangles inside the big one. Therefore,

\frac{4}{a} =\frac{a}{25\\}\\a^2=100\\a=10

The next one has the geometric mean of b, being a part of the smaller triangle on the left and the big triangle as a whole:

\frac{4}{b} =\frac{b}{29}\\b^2=116\\b=10.77

add the term that makes the given expression into a perfect square. write the result as the square of a bracketed expression c s
Molodets [167]
<h2>Perfect Squares</h2>

Perfect square formula/rules:

  • a^2+2ab+b^2=(a+b)^2
  • a^2-2ab+b^2=(a-b)^2

Trinomials are often organized like ax^2+bx+c.

The <em>b</em> value in this case is <em>c</em>, and it will always equal the square of half of the <em>b</em> value.

  • Perfect square trinomial: ax^2+bx+(\dfrac{b}{2})^2
  • or ax^2-bx+(\dfrac{b}{2})^2

<h2>Solving the Question</h2>

We're given:

  • c^2-4c

In a trinomial, we're given the ax^2 and bx values. <em>a</em> in this case is 1 and <em>b</em> in this case is 4. To find the third value by dividing 4 by 2 and squaring the quotient:

  • 4 ÷ 2 = 2
  • 2² = 4

Therefore, the term that we can add is + 4.

c^2-4c+4

To write this as the square of a bracketed expression, we can follow the rule a^2-2ab+b^2=(a-b)^2:

(c-2)^2

<h2>Answer</h2>

c^2-4c+4

(c-2)^2

What is the factored form of this expression?
gayaneshka [121]

Answer:

(x +  11 ) * ( x - 11)

Step-by-step explanation:

The expression:

x²   -    121

is a difference of squares

We notice that     √x²    =  x       and    √121    =   11

Then

( x²  -  121  )  =   ( x + 11 ) *  ( x  -  11 )

If we multiply

( x  +  11 ) *  ( x  -  11 )   =    x*x  - 11*x  +  11*x  - (11)*(11)

( x  +  11 ) *  ( x  -  11 )   =  x²  - 121

That is what we want to probe

Chance can wash the car in 2 hours, while Sandy can wash the same car in 4 hours. How many hours would it take for them to wash
aliya0001 [1]

Answer:  First Option is correct.

Step-by-step explanation:

Since we have given that

Number of hours Chance can wash the car = 2 hours

Number of hours Sandy can wash the car = 4 hours

Work done by Chance per hour is given by

\frac{1}{2}

Work done by Sandy per hour is given by

\frac{1}{4}

Work done by altogether per hour is given by

\frac{1}{2}+\frac{1}{4}\\\\=\frac{2+1}{4}\\\\=\frac{3}{4}

So, Number of hours they take if they together wash the car is given by

\frac{4}{3}

Hence, First Option is correct.
