The -1 affects the coefficient of the entire term.

Without the -1,
the term has a positive coefficient.
(3a)² = 9a²

However, with the -1,
the term has a negative coefficient.
-(3a)² = -9a²

Hello there! The value of x is 20 or -20

"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.

Step-by-step explanation:

$\large{ \frac{ {x}^{2} }{ {5}^{2} } = {4}^{2} }$

First, we simplify 5² and 4²

$\large{ \frac{ {x}^{2} }{25} = 16}$

Multiply the whole equation by 25 to get rid of the denominator.

$\large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\ \large{ {x}^{2} = 400}$

Square both sides and solve the equation.

$\large{ \sqrt{ {x}^{2} } = \pm{ \sqrt{400} }}$

Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.

$\large{x = \pm{20}}$

84> -4(6x-3) I don't know what the answer is. Can someone please help me?

nata0808 [166]

Answer:

x>−3

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

84>−24x+12

Step 2: Flip the equation.

−24x+12<84

Step 3: Subtract 12 from both sides.

−24x+12−12<84−12

−24x<72

Step 4: Divide both sides by -24.

−24x /−24 < 72 /−24

If a train travels 80 m/s in two hours and 20 minutes, how far has it traveled?

Alexxx [7]

Answer:

distance = 585600 m

Step-by-step explanation:

change 2 hours 20 minutes to seconds

2 hrs * 60 minutes/1hr * 60 sec/min = 7200 sec

20 minutes * 60 sec/min = 120 sec

2 hr 20 min = 7320 seconds

distance = rate * time

distance = 80 m/s * 7320 s = 585600 m
