Answer:
2√42 ≈ 12.961
Step-by-step explanation:
All of the right triangles are similar, so ...
short leg/long leg = BC/AC = AC/CD
AC² = BC·CD = 7·24 = 168
AC = √168 = 2√42
Answer:
2/16
Step-by-step explanation:
i just doubled he equation
Y= -2x + 4 , I might be wrong
Move all terms that don’t contain m to the right side and solve. M = 3
Answer:
C
Step-by-step explanation:
x + 2y = 21
4x + y = 21
Multiply the second equation by -2 to get:
-8x - 2y= -42 {Add this to the original equation; y's will be eliminated}
+ x + 2y = 21
-7x = -21
x = 3
see if y = 9 works . . .
3 + 2(9) = 21 and it does
