Answer:
C) AB = BC = CD = DA = 2√5
Step-by-step explanation:
Given
A(1, 4)
B(3, 0)
C(1, −4)
D(−1, 0)
We get the distance between point A and point B
AB = √((3-1)²+(0-4)²) = √20 = 2√5
BC = √((1-3)²+(-4-0)²) = √20 = 2√5
CD = √((-1-1)²+(0-(-4))²) = √20 = 2√5
DA = √((1-(-1))²+(4-0)²) = √20 = 2√5
C) AB = BC = CD = DA = 2√5
The third option is the answer
Answer:
(2,6)
Step-by-step explanation:
it will be 2and 6
y=-2+4x
2x-5y=_26
-18x+10=-26
y=-2+4x
x=2
y=-2+4x
y=-2+4(2)
y=6
Hey!! I got 90cm for the answer
Answer:
1.
2.
3.
4.
5.
6.
7.
8.
9.
10.
11.
12.
13.
14.
Step-by-step explanation:
Standard form means to put the terms in order based on their exponent (x³ -> x² -> x -> constant)
1. (6 - i) + (9 + 5i)
2. (7 + 3i) + (11 + 2i)
3. (12 + 4i) - (2 - 15i)
4. (3 - 7i) - (3 + 5i)
5. 7 - (2 - 3i) + 6i
6. -16 + (3 + 4i) - 4i
7. 3i(6-5i)
8. -2i(8+2i)
9. (-5 + i)(8 - 6i)
10. (3 - 6i)(-1 + 7i)
11. (2 + 5i)(2 - 5i)
12. (-3 - i)(-3 + i)
13. (4 + i) * 2
14. (5 - 9i) * 2
:p when I first started answering this I thought the parentheses were being multiplied every time and did 100x more work .-.
Hope it helps <3 :D
