Wewaii [24]

She can shake everyone's hand by 9/10 hands in 3 minutes.

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Glurpina is a polymorph alien and can grow extra limbs.

She has 3 hands and can shake everyone's hand at the alien conference in 10 minutes.

She can shake everyone's hand by 3 hands in 10 minutes.

She can shake everyone's hand by 1 hands in 10 / 3 minutes.

She can shake everyone's hand by how many extra hands in 3 minutes.

= 3/ 10 x 3

= 9/10

Thus, She can shake everyone's hand by 9/10 hands in 3 minutes.

Complete the square to form a perfect square trinomial x^2-14x+
fiasKO [112]
Answer: x^2 - 14x + 49

Explanation:

1) Divide the coefficient of x by 2:

14 / 2 = 7

2) so you have to add 7^2 = 49

x^2 - 14x + 49

3) that trinomial is equivalent to:

=> (x - 7)^2

4) prove that using the formula (a - b)^2 = a^2 - 2ab + b^2

(x - 7)^2  = x^2 - 14x + 49

Then you have to add 49 to complete the square. and form a perfect square trinomial.

Solve the linear equation. 8x+32=2(25x−15)−11x8x+32=2(25x−15)−11x
Bogdan [553]
It seems like you put the same equation up there twice, but no worries! :)

8x + 32 = 2(25x - 15) - 11x

Simplify.

8x + 32 = 50x - 30 - 11x

Add like terms.

8x + 32 = (50x - 11x) - 30

Simplify.

8x + 32 = 39x - 30

Now we must subtract 32 from both sides.

8x = 39x - 30 - 32

Then, subtract 39x from both sides.

8x - 39x = -30 - 32

Simplify.

-31x = -62

Finally, divide both sides by -31.

-31x ÷ -31 = -62 ÷ -31

Simplify.

x = 2
