5x = x^2 + 4
x^2 - 5x + 4 = 0
(x - 4)(x - 1) = 0
x = 4, 1
(x + 6)^2 = 100
x + 6 = +/1 sqrt100
x + 6 = +/- 10
x = 4, -16

Answer:

Grant will make $60 from selling 12 magazines.
Step-by-step explanation:
Let m represent number of magazine sold and A represent amount of money earned.
We have been given that Grant earns $5 for each magazine he sells. So amount earned from m magazines would be 5 times m that is
dollars.
Now, we will equate total amount earned by Grant with A as:

Therefore, our required equation would be
.
To find the amount earned by Grant by selling 12 magazines, we will substitute
in our equation as:


Therefore, Grant will make $60 from selling 12 magazines.
Answer:
The area of the whole field is 54400yd^2
Step-by-step explanation:
says that I add 10 yards in each zone, that means that 10 yards is added twice at 1000 yards
1000yd + 2*10yd = 1020yd
we have to know that one yard equals 3 feet
so to have the length in feet we only multiply it by 3
1020 * 3 = 3060ft
Now that we know the length and width of the court, we can calculate the area by multiplying them
a = b * h
a = 3060ft * 160ft
a = 489600 ft^2
the result is in square feet
if we want it in square yards we just have to divide 2 times by 3
489600/(3*3) = 54400yd^2
