Answer:
Step-by-step explanation:
<u>According the the picture we have:</u>
- The triangles have two congruent sides and one non-included angle.
It means we don't have sufficient information to state the triangles are congruent.
Correct choice is B
[x-1]=5x+10
We have two equations:
1) x-1=5x+10
x-1=5x+10
x-5x=10+1
-4x=11
x=-11/4
2) x-1=-(5x+10)
x-1=-(5x+10)
x-1=-5x-10
x+5x=-10+1
6x=-9
x=-9/6=-3/2
we have two possible solutions:
solution₁; x=-11/4
solution₂: x=-3/2
we check it out:
1) x=-11/4
[x-1]=5x+10
[-11/4 - 1]=5(-11/4)+10
[(-11-4)/4]=-55/4 + 10
[-15/4]=(-55+40) /4
15/4≠-15/4 This solution don´t work.
2) x=-3/2
[x-1]=5x+10
[-3/2 - 1]=5(-3/2)+10
[(-3-2)/2]=-15/2 + 10
[-5/2]=(-15+20)/2
5/2=5/2; this solution works.
Therefore:
Answer: x=-3/2.
Answer:
6x ² - 10x - 56
Step-by-step explanation:
(3x -7) (2x +8)
To expand this, each term in the first bracket would multiply the other bracket.
3x(2x +8) -7( 2x + 8)
6x ² + 24x - 14x - 56
6x ² + 10x - 56

Answer:
Step-by-step explanation: 1) 14.5 bc
We have the equation:
43.5 ÷ 3 = 14.500
Calculated to 3 decimal places.
2) They are all the same because they are the same numbers but in different places.
i hope this helps! =3
.00007
If it is to the negative power, you live the decimal point to the left (if positive, move to the right). In the case we move the decimal point 5 places to the left of 7. This results in .00007.
