Answer:
x=127°
Step-by-step explanation:
The sum of the interior angles of a polygon is given by:
For a 6- sided polygon, the sum of interior angles is
We add the interior angles and equate them to 720°
x+112°+133°+128°+100°+120°=720°
x+593=720
x=720-593
x=127°
X^2+6x+8=0
To write the above in the form of (x-p)^2=q we proceed as follows:
i] Re-write the expression:
x^2+6x=-8
ii] Calculate for the vale of c.
c=(b/2a)²
given that:
b=6, and a=1
thus
c=(6/2*1)^2=9
iii]
Add 9 on both sides of the equation from i
x^2+6x+9=-8+9
simplifying we get:
x^2+6x+9=1
factoring the LHS we get:
(x+3)(x+3)=1
(x+3)²=1
The above is in the form of:
(x-p)²=q
where:
p=3 and q=1
Answer:
24 ( 12 -3x)
Step-by-step explanation:
(4x3 + 7x2 – 2) (2x2 – 3x + 8)
(12 + 14 - 2) (4 - 3x + 8)
(26-2) (12 - 3x)
24 (12 -3x)
Answer:
x=4, y=6, z=5
Step-by-step explanation:
x = 8/2 = 4
y = 12/2 =6
z = 10/2 = 5
