Answer:
2 + 6i
Step-by-step explanation:
It’s the same numbers with an opposite sign
Answer: 3 x 7
Explanation:
So the question is asking you to multiply two prime numbers in order to get 21.
Since 3 and 7 are both prime numbers, you can express 21 as 3 x 7

Answer:
5.95 inches
Step-by-step explanation:
So, the problem says that the piece of ply wood was cut into 4 equal sections and that the original length was 23.8 inches long. This is a simple equation. All you have to do is cut, or divide, 23.8 into 4 pieces. so 23.8 ÷ 4. So Ronnie cut the ply wood into 4 pieces that measure 5.95 inches each.

Answer:
The perpendicular equation is y = -3x -21
Step-by-step explanation:
Perpendicular lines have the exact opposite slope as the other equation and they never have the same y-intercept.
To find the perpendicular slope just look at the slope in the original equation and get the exact opposite.
First let's simplify the equation.
-5 + x = 3y (divide by 3 on both sides to get y by itself)
-5/3 + 1/3x = y or y = 1/3x + 5/3
The exact opposite of this slope would be -3.
Now plug in the point you were given so that we can find the y-intercept.
6 = -3(-9) + b (b = y-intercept)
6 = 27 + b (subtract 27 on both sides)
-21 = b
So the perpendicular equation looks like this.
y = -3x -21
