Answer:
You can just switch them around, 68 + 76×
Given:
The figure of a quadrilateral ABCD.
To find:
The supplement of angle ABC.
Solution:
We know that, two angles are called supplementary angles if their sum is 180 degrees.


So,
is not a supplement of
.


So,
is not a supplement of
.



So,
is a supplement of
.
In the same way
.
So,
is not a supplement of
.
Therefore, the correct option is C.
C = 2 <span>π r
C = 2 </span>π <span>(2.2)
C = 4.4 </span><span>π (in term of pi)
answer
4.4</span><span>π </span>
I'll just factor the above equation.
x² + 18x + 80
x² ⇒ x * x
80
can be:
1 x 80
2 x 40
4 x 20
5 x 16
8 x 10 Correct pair
(x+8)(x+10)
x(x+10) +8(x+10) ⇒ x² + 10x + 8x + 80 = x² + 18x + 80
x+8 = 0
x = -8
x+10 = 0
x = -10
x = -8
(-8)² + 18(-8) + 80 = 0
64 - 144 + 80 = 0
144 - 144 = 0
0 = 0
(-10)² + 18(-10) + 80 = 0
100 - 180 + 80 = 0
180 - 180 = 0
0 = 0
I think the algebra tiles will not be a good tool to use to factor the quadratic equation because the equation is not a perfect square quadratic equation.
The expression for the perimeter would be
2(x) + 2(2x+7)
which can be simplified to 2x+4x+14
which equals 6x+14
