Answer: The measure of fourteenth angle is 120°.
Step-by-step explanation:
Since we have given that
Total number of angles in 14 gon = 14
Sum of measures of 13 angles = 2040°
As we know that sum of all angles in 14 gon would be
So, the measure of fourteenth angle would be
Hence, the measure of fourteenth angle is 120°.
Answer:
$33
Step-by-step explanation:
55 divided by 5 is 11, so each shirt costs $11. So that means 3 shirts would be $33.
Answer:
y = 1/3(x + 5)^2 - 4
Step-by-step explanation:
The general vertex form is;
y = a(x-h)^2 + k
From the question, (h,k) are the coordinates of the vertex which is (-5,-4)
So we have
y = a(x + 5)^2 -4
So we need to get the leading coefficient
Simply substitute the point it passes through
x = -2 and y = -1
-1 = a(-2 + 5)^2 - 4
-1 = a(3)^2 -4
-1 = 9a -4
9a = 4-1
9a = 3
a = 3/9
a = 1/3
So the equation is;
y = 1/3(x + 5)^2 - 4
Answer:
x=5 or -5
Step-by-step explanation:
4x^2=100
x^2=25
x=5 or -5
Answer:
C
Step-by-step explanation:
(2x-3)(4x+5)
=2x(4x+5)-3(4x+5)
=8x^2+10x-12x-15
=8x^2-2x-15
