b. Every 24 minutes

Step-by-step explanation:

A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.

The first step is to:

Find and list multiples of each time each neon sign blinks.

This means, we find the Multiples of 6 and 8

Multiples of 6:

6, 12, 18, 24, 30, 36

Multiples of 8:

8, 16, 24, 32, 40

The first and common multiple of 6 and 8.

Therefore, the Least common multiple [LCM(6, 8) ] = 24

Hence, they often blink at the same time every 24 minutes.

Therefore, option b.Every 24 minutes is correct.

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.

Dvinal [7]

Answer:

t+0.07t=t(1+0.07)=t(1.07)=1.07t

Step-by-step explanation:

There are a couple of  equivalent expressions to the function t+0.07t. For example:

t+0.07t

Factor:

t+0.07t=t(1+0.07)

If you add the terms inside the parentheses:

t(1+0.07)=t(1.07)

Basically you can add the like terms from the start and get the same result.

t+0.07t=1.07t

Therefore:

t+0.07t=t(1+0.07)=t(1.07)=1.07t
