Answer:
x = 20
Step-by-step explanation:
3 (x-8) +2x = 76
3x - 24 +2x = 76
3x+2x = 76+24
5x = 100
x = 20
The distance from a to c is ten units
(32 + 90 + 92 + 82 + 64 + x) / 6 = 85
(360 + x) / 6 = 85
360 + x = 85 * 6
360 + x = 510
x = 510 - 360
x = 150 <===
Answer:
<h2>
A = (1,-5)</h2>
Step-by-step explanation:
Let the midpoint of the two points A (x₁, y₁) and B(-5, 5) be M(2, 0)
Using the formula for calculating the midpoints of two coordinates
(X₁, Y₁) = 

Given if (X₁, Y₁) is the midpoint, then X₁ = 2, Y₁ = 0
x₂ = -5 and y₂ = 5
Substituting this given values into the equation above to get the unknown coordinate;

Similarly;

The coordinate of A = (1,-5)
Here we are given
<span>8x^3-27
now making both as a cube root
</span><span>(2x)^3-(3)^3
using formula cube root
</span><span> a^3-b^3=(a-b)(a^2+ab+b^2)
</span>where
a=2x
b=3
now putting these values
<span>2x^3-3^3=(2x-3)(2x^2+2x*3+3^2)
simplifying
</span>2x^3-3^3=<span>(2x-3)(4x^2+6x+9)
</span>hence the right answer is
2x^3-3^3=<span>(2x-3)(4x^2+6x+9)</span>
