Answer:
(2,2), 24 units squared
Step-by-step explanation:
D is at (2,2) because it would make Line AD equal to line BC and line AB equal to line CD, which would make a rectangle.
Area= length x width
A= 6 x 4
A=24 units squared
Good Luck!
Answer:
(7, -4.5)
Step-by-step explanation:
25−x=−4y ---> x=25+4y
3x−2y=30
use x to substitute into the second equation
3 (25+4y)-2y = 30
75+12y-2y=30
75+10y=30
10y=-45
y=-4.5
3x-2(-4.5)=30
3x+9=30
3x=21
x=7
check:
25-7=-4*-4.5
18=18 (yes)
3*7-2*-4.5=30
21+9=30
30=30 (yes)
Step-by-step explanation:
48/4+[6+{12/2 of 3}-4]+20
48/4+[6+18-4]+20
12+20+20
52
Wat grade are uu in?.....
You have to use Pythagorean theorem
12^2+20^2 = x^2
sqrt(144*400) = x^2
sqrt(544) = x
X = 4 sqrt(34)
