Check the picture below.
now, looking at the picture's scaling, from the lower-left-corner up to 20 is 5 squares, the rectangles you see in the picture are 40 units each, namely 10 squares. Every square is 4 units, it goes up 12 squares, namely 48 units, and goes to the right by 30 squares plus 4 more, 34 squares, that's 136 units.
well, if we were to make a triangle for the slope, check the picture, it'd look like that.
Why is the slope negative? well, because is going down from left to right.
C is the answer f(2)= 6*2+2=14
1. To find the square root, you have to square root them both.
Square root of 324 is 18, so x=-18, 1818
2. Divide 49 by 9. 49/9=5.44 then find the square root of 5.44 which is 2.3, x=-2.3, 2.3.
3. To do this one it is one of either 2 or 4 because it is not a perfect square, it can break down to square root of 16 and square root of 6, which then makes it +-4 square root 6.
4. This one is simple the square root of 34 is 5.8
5. Subtract each by 5 to get 6y^2=215 then divide each by 6. Y^2=34.8 then square root. Which makes y=+-5.9. Hope this helped.
Answer:
30
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
The conjugate of - 2 + 2i is - 2 - 2i, hence
(- 2 + 2i)(- 2 - 2i) ← expand factors using FOIL
= 4 + 4i - 4i - 4i² [ note i² = - 1 ]
= 4 + 4
= 8
