The correct answer is x = 12

This is not correct. There are 180° in a triangle, not in each angle. To be 180°, the angle would need to be completely straight (not a triangle).

Since we know this is an equilateral triangle (all three sides are congruent to one another), it is also equiangular (all three angles are congruent to one another). There are 180° in a triangle -- which has 3 angles -- so divide that by 3 to get the measure of the angle (60°).

5x = 60

In the equation x^2 + mx + n = 0, m and m are integers. The only possible value for x is -3. What is the value of m?
Law Incorporation [45]

If there is only one solution, at x=-3, then the factor of (x+3) must be repeated. The equation must be equivalent to

... (x +3)² = 0

This multiplies out to give

... x² +6x +9 = 0

The value of m is 6.

_____

For finding the square of a binomial, you can either use the special form you have memorized:

... (x +a)² + x² +2ax + a²

or you can use the distributive property.

... (x +a)² = x(x +a) +a(x +a)

... = x² +ax +ax +a² = x² +2ax +a²

Need some help on my homework can anyone help :P
kati45 [8]

Answer:

Well, first you'd want to isolate your Ys, so that

-3y≤12-2x

&

y≥1-2x


Now they look like your common (y=mx+b) equations, so you should be able to graph from there. I don't quite remember how the shadowing works for inequalities, SO, go to desmos.com, type in the equations, and voila!

HELP PLZ THANK U ILY SM YOUR AMAZING LITERALLY INCREDIBLE
CaHeK987 [17]

Answer:

our inputs are 3 & 1/2

Step-by-step explanation:

the ? is the slope and the slope is equal to 1/2 so

?=1/2

the point slope formula is

(y-y1)=m(x-x1)  (x1,y1)--> a point on the line  m--> slope

so we chose (x1,y1) as (3,0)

when we plug that in we get

y-0=1/2(x-3)

so our inputs are 3 & 1/2
