Answer : B
x^2-9x+14
Lets factor 
We find out two factors whose product is +14 and sum is -9
Two factors are -2 and -7, we split the middle term -9x using -2 and -7
Group first two terms and last two terms
Then factor out GCF from each term
so x-2 is one of the factor
Answer:
See proof below
Step-by-step explanation:
Two triangles are said to be congruent if one of the 4 following rules is valid
- The three sides are equal
- The three angles are equal
- Two angles are the same and a corresponding side is the same
- Two sides are equal and the angle between the two sides is equal
Let's consider the two triangles ΔABC and ΔAED.
ΔABC sides are AB, BC and AC
ΔAED sides are AD, AE and ED
We have AE = AC and EB = CD
So AE + EB = AC + CD
But AE + EB = AB and AC+CD = AD
We have
AB of ΔABC = AD of ΔAED
AC of ΔABC = AE of ΔAED
Thus two sides the these two triangles. In order to prove that the triangles are congruent by rule 4, we have to prove that the angle between the sides is also equal. We see that the common angle is ∡BAC = ∡EAC
So triangles ΔABC and ΔAED are congruent
That means all 3 sides of these triangles are equal as well as all the angles
Since BC is the third side of ΔABC and ED the third side of ΔAED, it follows that
BC = ED Proved
Steps:
Shape: Regular octagon
Solved for area
Side= 10cm
Formula: A=2(1√+2)a2
Round to the nearest tenth = 482.8
Description:
Using the formula for the area of Regular octagon ( A=2(1√+2)a2) We have to calculate the side length that is 10 cm. Your answer will equal as A≈482.84cm² after you calculate. Since it says to round to the nearest tenth your answer will come as 482.8.
Answer: A≈482.84cm²
Round to the nearest tenth = 482.8
