Answer:
X will equal 10 x=10
Step-by-step explanation:
First subtract 100 from both sides to get x^2-20x=-100 then find c. (-b/2)^2 is the formula. then c=100 so add 100 to both sides. x^2-20x+100=200. Then Factor. (x-10)^2=0 is what you should get. then do square root. x-10=0. So now add 10 to both sides and you get x=10. Tada!
Sound, earthquakes, the brightness of stars, and chemistry, such as pH balance, a measure of acidity and alkalinity, are all instances of this.
In order to figure this out, you must solve the equation.
1-6x=7 (given)
-6x=6 (subtract 1 from both sides)
X=-1 (divide both sides by -6)
The answer is no.

Step-by-step explanation:
The heights of plant A and plant B will be equal on the day 8.
<h3>How to find the heights of the trees?</h3>
The height of the tree can be found as follows:
The equation for plant A can be described as follows:
y = 1 + 0.5x
where
x = number of days
y = height
The equation for plant B can be described as follows:
y = 3 + 0.25x
Therefore, for the height to be equal
1 + 0.5x = 3 + 0.25x
1 - 3 = 0.25x - 0.5x
-2 = -0.25x
x = 2 / 0.25
x = 8 days
