Answer:
72.4 and 107.6
Step-by-step explanation:
on delta math
Answer:
is that the number in the middle = then more the -3 to 2x add in you get 1 being y=1 so 1 -3 is 2x
Answer:
12
Step-by-step explanation:
AC = AB + BC
Since we know what each variable equals, we can write out the equation as shown:
52 = 8X + 8 + 2X + 4
Combining like terms:
52 = 10X + 12
Subtract 12 from both sides:
40 = 10X
Divide by 10:
X = 4
Now that we know X, we can figure out BC
BC = 2(4) + 4
BC = 8 + 4
BC = 12
Therefore BC is 12.
<span>x^2 – 4x – 5 = 0
(x -5)(x +1) = 0
x - 5 = 0; x = 5
x +1 = 0; x = -1
answer: x = -1 and x = 5</span>
