Answer:
10.2 cm²
Step-by-step explanation:
regular hexagon made up of six equilateral triangles
A = (2 × 1.7) /2 × 6 = 10.2
or by the side length
A = 3√3/2 * 2² = 10.3
So what you do is distribute the invisible -1 in front of the second parenthasees set and add like terms
remember
x^2+3x^2=4x^2
-(3+4x-x^2)=-1(3x+4x-x^2)=-3-4x+x^2
so first distribute the negative 1
-1(-4f^2-3f+6)=4f^2+3f-6
add
12f^2-9f+15+4f+3f-6
group like terms
12f^2+4f^2-9f+3f+15-6
add
16f^2-6f+9
aswer is 16f^2-6f+9
Answer: On Thursday the low temperature change the most.
Explanation :
From the given table we can conclude that change is the lowest in Thursday .
And there is no matter if it is positive or negative
Because change defines final - initial only i.e. difference between final and initial
So, we consider absolute value only.
According to which Thursday has the atmost change i.e 4.1 which is the lowest amongst the other .
So ,on Thursday the low temperature change the most.
The number should be 649392728192
