Ok so the question has already been answered by someone but i wanna give you some advice... it’s called ✨photomath✨ and you can take a picture of the problem or type it in... it would have been able to solve this equation right away, so you wouldn’t have had to wait for someone to answer. have a great day :)
Answer:
(5x-2)(5x+2)
Step-by-step explanation:
Differences of squares is basically (a2-b2) = (a-b) (a+b)
a = 5x and b = 2 in this case
Brainliest is appreciated :)
Answer:
x = 12
Step-by-step explanation:
Step 1: Add 9 to both sides.
Step 2: Divide both sides by 7.
Step 3: Check if solution is correct.
Therefore, x = 12.

Answer:
A = π(14t)²
Step-by-step explanation:
The radius is increasing at the rate of 14 cm per second.
We need to find the formula for the area A of the circle as the function of time t.
Initial area of the circle,
A = πr², where r is the radius of the circle
Area as a function of t will be :
A = π(14t)²
Here, 14t is the radius of the wave.
