Answer:
x^2 - 6x + 147 so the coefficient is 1
Step-by-step explanation:
First, simplify the equation.
1. 2/3x(2x-3) = (2x/3)(2x-3)-(x-7)(x+7)
2. 2x-3(2x/3) = (2x(2x-3)) - (x-7)(x+7)
3. Expand -(x-7)(x+7) = -x^2+49
Combine to get (x^2 - 6x)/3 +49
Simplify to get x^2 - 6x + 147. The coefficient of the quadratic term is one.
Answer:
The length of the missing leg is 56 meters.
Step-by-step explanation:
Use the Pythagorean theorem to figure out the leg of the missing leg.
Formula: a^2+b^2=c^2, given a=leg, b=leg, and c=hypotenuse
The hypotenuse is 65 meters, and one of the legs is 33 meters, so plug it into the formula and solve for a.
a^2+33^2=65^2
a^2+1089=4225
a^2=3136
Take the square root of both sides, and you get 56 meters.
Answer:
$12.56
Step-by-step explanation:
$50.24 divided by the 4 friends = $12.56
I divided the total cost by the amount of friends who went to the museum and so I did $50.24 divided by the 4 friends = $12.56.
Remember, a number's additive inverse is simply its opposite.
Let's say we have a number a.
The opposite of a is -a, and the opposite of -a is a.
Thus, the additive inverse of
is

Feel free to ask if you have any doubts.
you have negative -12
turn this into a positive (12)
12 plus 18
= 30
