The equation shown below involves a perfect square trinomial. 4x2 + 20x + 25 = 7 Which of the following is a step in solving this equation? A. Take the square root of both sides B. Subtract 25 from both sides C. Square both sides D. Divide both sides by 4

Answers

4 x^2 + 20 x + 25 = 7
Divide both sides by 4:
x^2 + 5 x + 25/4 = 7/4
Write the left-hand side as a square:
(x + 5/2)^2 = 7/4
Take the square root of both sides:
x + 5/2 = sqrt(7)/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
x = sqrt(7)/2 - 5/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
Answer:  x = sqrt(7)/2 - 5/2 or x = -5/2 - sqrt(7)/2

Step-by-step explanation:

a^(m)*a^(n)=a^(m+n)\n\n9^(10)*9^(x)=9^(10+x)

In exponent multiplication, if the bases are same then add the exponents.

\small \sf \leadsto 9 {}^(10 +x)

Step-by-step explanation:

Using exponent's product rule

\small \sf \: x {}^(n) * x {}^(m) = x {}^(n + m)

\small \sf \leadsto \: 9 {}^(10) * 9 {}^(x)

\small \sf \leadsto 9 {}^(10 + x)

What expression can be used to calculate the rate per minute at which the air freshener dispenses sprays?

Answers

okay so lets say that it sprays every 12 seconds so what you need to do is divide 12 with 60 so  60÷12=5 so it sprays 5 times per minute 

You didn't give any answers, but, I hope this will help you out a bit:


for example, if the air freshener sprays 3 times every 20 minutes,

here are our points:

(20,3), (40,6), (60,9), (80,12)

lets take the second and third point to find the slope.

(9-6)/(60-20) = (3)/(40)

3/40 would be the slope.
