8, because you’re doubling the numbers so 3x2=6 and 4x2=8.
Step-by-step explanation:
Amount of water left = 250 - 9x.
A cube, is made off 6 squarial faces, so all faces on that cube, are squares, the front, back, left, right, top and bottom.
a square has all equal sides, and also all right angles, so all angles in a square are 90°. Let's say the sides are "x" long.
now, if we run a plane on that cube diagonally, check the picture below, the diagonal side at the bottom, by usin the 45-45-90 rule as you see it there, will be x√2.
let's keep in mind that, "x" is opposite side of that angle θ, and then x√2 will be the adjacent side of it.
and we can use those two to get the tangent and then the inverse tangent to get the value, as you see it in the picture.
if you need the angle in radians, run the inverse tangent again, just make sure your calculator is in radians mode.
The value of x will be2.217 and PR will be 13.085 units.
<h3>What is a line segment?</h3>
A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
Given that,
Line PQ consists of two segments PR and RQ
So,
PQ = PR + RQ
17 = 5x+2 + x² - 1
x² + 5x - 16 = 0
The roots of the equation will be
x = [-5 + √(25 + 64) ] ÷ 2
x = 2.217
Now,
PR = 5(2.217) + 2 = 13.085
Hence "The value of x will be2.217 and PR will be 13.085 units".
