Answer:
Step-by-step explanation:
<u>TRUE</u>
All isosceles triangles have at least 2 acute angles due to 2 sides are equal.
The exterior angle of an equilateral triangle is obtuse.
If the perimeter of an equilateral triangle is P, then the length of each of the sides is P/3.
<u>FALSE</u>
All isosceles triangles are equilateral triangles.
If you know the length of one of the legs of an isosceles triangle, you can determine it’s the perimeter
Answer:
-12
Step-by-step explanation:
Just do -3 times 4 which gives you -12
Answer:
Step-by-step explanation:
Given is a function
Since leading term is positive,
the parabola is open up.
Let us write this in vertex form after completing the square
Hence we get vertex= (-5/2,-1/4)
Since this is a parabola open up we have the minimum point is only one at x=-5/2
So we have the function decreasing for x<-2.5 and increasing for x>-2.5
Decreases in
Increases in
For vertex form, half the middle term and square it
(x2 + 4x + 16) + 18 - 16
so...
(x + 4) ^2 + 2
To find the answer you could do 256 divided by 4 and that gives you the answer which is 64 to check the math you can multiply 64 times 4 and if it comes out as 256 then you have your answer.
Hope this answers your question!
