Answer:
<h3>A. x=5*8</h3>Step-by-step explanation:
Isolate the term of x from one side of the equation.
<u>First, you have to multiply by 8 from both sides.</u>
<u />
<u>Solve.</u>
<u />
<u>Multiply the numbers from left to right.</u>
5*8=40
<u>Therefore, the correct answer is "A. x=5*8".</u>
I hope this helps. Let me know if you have any questions.
If the endpoints of DE where D(-3, y) and E(x, 6) with the midpoint M(4, 2), the length of DE is 16.12 units
The formula for calculating the midpoint is expressed as;
For the x-coordinate points:
X = -3+x/2
4 * 2 = -3 + x
8 = -3 + x
x = 8 + 3
x = 11
Get the value of y;
2 = y+6/2
y+6 = 2 * 2
y + 6 = 4
y = 4 - 6
y = -2
Hence the coordinates of D and E are D(-3, -2) and E(11, 6)
Hence the length of DE is 16.12 units
