Answer:

x=2√2 or x=−2√2

^^Both are correct.^^

Step-by-step explanation:

Let's solve your equation step-by-step.

4x^2−25=7

Step 1: Add 25 to both sides.

4x^2−25+25=7+25

4x^2=32

Step 2: Divide both sides by 4.

4x2 /4 = 32 /4

x^2=8

Step 3: Take square root.

x=±√8

x=2√2 or x=−2√2

A movie theater earned $3,600 in sold-out ticket sales for the premiere of a new movie. VIP tickets cost $20 per person and regu

julia-pushkina [17]

There are 300 seats in the theater.

Step-by-step explanation:

Given,

Cost of one VIP ticket = $20

Cost of one regular ticket = $8

Worth of sold out tickets = $3600

Let,

x represent the number of VIP tickets sold

y represent the number of regular tickets sold

20x+8y=3600 Eqn 1

y = 2x Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$20x+8(2x)=3600\\20x+16x=3600\\36x=3600$

Dividing both sides by 36

$\frac{36x}{36}=\frac{3600}{36}\\x=100$

Putting x=100 in Eqn 2

$y=2(100)\\y=200$

Total = x+y = 100+200 = 300

There are 300 seats in the theater.

True of False: (log x)^2=2log x. Explain your answer and show your work

Lubov Fominskaja [6]

False.
Only log(x^2)=2log(x)
For example, let x=10
(log(10))^2=1^2=1
yet 2log(10)=2*1=2

(7*10^5)^2 simplified in scientific notation

coldgirl [10]

♥ Lets solve this:
(7*10^5)^2(7*10^5)^2
Starting with 10^5
10*10*10*10*10
We get 100000
Now we have 7*100000
Solve for that:
We get 700000
Now we have 700000^2
Solve for that
We get 490000000000
and in Scientific notation that is
4.9*10^11
