X = 12
because if you notice, each of the angles have a little arc in the corner, which means they are congruent. if all three angles are congruent, that means each angle is 60° because each triangle has a maximum value of 180°. therefore, this means it is an equilateral triangle.
that being said, each side must be equal as well. so, you can use any two sides to find x by using each one on a different side of an equation, then isolating and solving.
5x - 22 = 3x + 2 = 4x - 10
so
5x - 22 = 3x + 2
3x + 2 = 4x - 10
4x - 10 = 5x - 22
whichever one you solve for, x = 12. and if you plug in that number for x, each side equals the same number = 38

Step-by-step explanation:
x = original salary
$3800 = (1-9%)x = (1-0.09)x = 0.91x
x = $3800/0.91 = $4175.82
Answer:
1708.58658058
Step-by-step explanation:
Total surface area formula = (π×r²)+(π×r×s)
r = radius
s = slant height
So we substitute the values into the formula (π×r²)+(π×r×s)
(π×14.2²)+(π×14.2×24.1) = 1708.58658058
Answer:
d. 18x^3-27x^2y
Step-by-step explanation:
(3x)^2(2x-3y)
work out the first term
9x^2(2x-3y)
distribute
18x^3-27x^2y
