The equation 2x^2+12x=4 is written in the form of 2(x-p)^2+q=0. what is the value of q?

hram777 [196]

1) Factor out the coefficient 2: 2x^2+12x=4 => 2(x^2 + 6x) = 4

2) Complete the square of x^2 + 6x: x^2 + 6x + 9 - 9. Then:

2(x^2 + 6x + 9 - 9) = 4

3) Rewrite the square as the square of a binomial:

2( [x+3]^2 - 9) = 4, or

2([x+3]^2) = 22, or

2( [x+3]^2 ) - 22 = 0

The value of q is -22.

You are remodeling your kitchen. You’ve contacted two tiling companies who gladly told you how long it took their workers to til

Papessa [141]

As given, let Jim's rate = x

Let Pete's rate =y

Jim completed half the floor in 12 hours so it's $12\times rate$ = 12x

Pete completed the other half of the floor in 10 hours so its $10\times rate$ =10y

As floor area is equal so,

$12x=10y$ .............(1)

Now, given is that Pete can lay 25 more tiles per hour than Jim, this gives=

$y=x+25$ ...... (2)

Putting the value of y from equation (2) in equation (1) , we get

$12x=10(x+25)$

So, the equation is : $12x=10(x+25)$

If you want to solve it, it becomes:

$12x=10x+250$

$2x=250$

$x=125$

Hence, Jim can lay 125 tiles and Pete can lay 25 more so 125+25=150 tiles.
