1) 6.6 * 3.3 = 21.78
2) (10^ - 2 )*(10^ - 4) = 10 ^ ( -2 - 4) = 10 ^ - 6
3) result: 21.78 * 10 ^ - 6
4) to convert to standard form run the period on space to the lef and multiply the ten base by 10 =>
2.178 * 10 ^ - 5
Answer: 2.178 * 10 ^ - 5

Answer:
x = 30
Step-by-step explanation:
So we're going to start by finding the other angles of the triangle which x is part of. So we know that a line adds up to 180 degrees. So we can find the angle that's close to N. If you know which one I'm talking about.
105 + 45 = 150. So then we can subtract 150 from 180
180 - 150 = 30
And for the angle at angle L, it's also 90 degrees.
So we know that the angles that add up so far are 120.
Now we'll make an equation:
2x + 120 = 180
Because all angles of a triangle add up to 180
So we subtract 120 from both sides
2x = 60
Now we divide 2 form both sides.
x = 30
So, x = 30
Answer: y= -2; x = 8
Step-by-step explanation:
X=-4y.......equation 1
3x+2y=20......equation 2
Substitute the value of x into equation 2
3 (-4y) + 2y = 20
-12y + 2y = 20
-10y = 20
Divide both sides by -10
y = 20/-10
y = -2
Substitute the value of y into equation 1 to get the value of x
x = - 4(-2)
x = 8
I hope this helps greatly, please mark as brainliest answer.
