<h3>
Answer:</h3>
C. 4(x-3)-x
<h3>
Step-by-step explanation:</h3>
All of the given expressions are equivalent to 3x+12 except selection C. Using that in your equation makes it be ...
... 3(x +1) +9 = 4(x -3) -x
... 3x +12 = 3x -12
... 12 = -12 . . . . . <em>false</em>
There is no value of x that will make this true, hence NO SOLUTION.
_____
<em>Comment on the other choices</em>
3x+12 = 3x+12 has an <em>infinite number of solutions</em>, as <u><em>any</em></u> value of x will make this true.
Answer:
B
Step-by-step explanation:
the equal is correctly
3x + 1 = 2x + 4
what was done now :
2 x-blocks (2x) subtracted from the right side, and 1 numbered block subtracted from the left side.
to reestablish balance and equality of both sides, we need to do more the exact same things - just in the other sides.
2 x-blocks subtracted from the LEFT side, and 1 numbered block subtracted from the RIGHT side.
and that is answer B.
Answer:
37
Step-by-step explanation:
The calculation of size for a new television is shown below:-
With the help of Pythagoras theorem

where
h indicates hypotenuse which is the diagonal length
b indicates the base which is the length of the horizontal side
p indicates perpendicular which is the TV length of the vertical side.

now, we will put the values into the above formula

Which gives result
= 36.7
or
= 37
Answer:
(a)
Step-by-step explanation:
The base angles theorem states that if 2 sides of a triangle are congruent, that is an isosceles triangle then the angles opposite these sides are equal.
