Answer:
The answer is 2.
Step-by-step explanation:
Given: - 6 - (-6) + 7 + ( - 4) + ( - 1)
= - 6 + 6 + 7 - 4 - 1
= 6 + 7 - 6 - 4 - 1
= (6 + 7) - (6 + 4 + 1)
= 13 - 11
= 2
Hence, the answer.
Yes 28/30 is bigger than 4/5.
Is there a chart involved
I always prefer factoring, if there are simple factors.
There are simple factors here.
x² + 11x + 18 = 0
(x + 2) (x + 9) = 0
The left side is zero if either factor is zero.
First factor:
x + 2 = 0
<u>x = -2</u>
Second factor:
x + 9 = 0
<u>x = -9 </u>
Through a geometric proof, 2(55x-1) = 107x+1
110x-2=107x+1
3x=3
x=1
Angle DEF is 54 degrees.
