580/2=290
the airplane flies 290 per half hour.
Answer:
-1 5/28
Step-by-step explanation:
-3/7 + (-3/4)
Get a common denominator of 28
-3/7 *4/4 = -12/28
-3/4 *7/7 = -21/28
-12/28 + -21/28
-33/28
-28/28 - 5/28
-1 5/28
Answer:

Step-by-step explanation:
intercepts the x-axis at these 2 points:

⇒ 6 and 1/2 are roots ie; if you insert
or
into the equation of g(x) you will obtain a 0.

now in order for 0 to appear we should have 
now in order for 0 to appear we should have 
but
doesn't appear in any of these, but its multiple of 2 is there:

Therefore the function;

Answer:
x = -2 or x = -1/2
Step-by-step explanation:
We can just set up an equation where the quadratic is equal to -10, and then solve the equation:

Now, factor:

Answer:

Step-by-step explanation:
In parallelogram ABCD, BC=AD
Given:
BC=(6-x) units
AD =(x+2) units
Therefore:
6-x=x+2
x+x=6-2
2x=4
x=2
BC=(6-x) units
=(6-2) units
BC=4 units
The opposite angles of a parallelogram are equal. Therefore:


Therefore, the match is:
