We can write it down as:
5 = 2x - 3 / + 3 (both sides)
8 = 2x / : 2 (both sides)
x = 4
Bob has 4 CDs. Let's check it:
5 = 2 * 4 - 3
5 = 8 - 3
5 = 5
Correct.
The expression which is not equivalent to the provided expression is expression number 1, x²(-4x+1)-2(3x-4).
<h3>What is the equivalent expression?</h3>
Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
The expression given in the problem is
f(x)=-4x³+x²-6x+8
The option given as,
- (1) x² (-4x+1)-2(3x-4)
- (2) x(-4x²- x + 6) + 8
- (3) -4x³ + (x - 2)(x - 4)
- (4) -4(x³ - 2) + x(x - 6)
From the given expression, if we take out <em>x </em>from the first three terms, it looks like option 2.
f(x)=-4x³+x²-6x+8
f(x)=x(-4x²+x-6)+8
From the given expression, if the last three terms factored, it looks like option 3.
f(x)=-4x³+x²-6x+8
f(x)=-4x³+x^2-4x-2x+8
f(x)=-4x³+x(x-4)-2(x-4)
f(x)=-4x³+(x-4)(x-2)
Rearrange the given expression, and make it looks like option 4.
f(x)=-4x³+x²-6x+8
f(x)=-4x²+8+x²-6x
f(x)=-4(x³-2)+x(x-6)
Thus, the expression which is not equivalent to the provided expression is expression number 1, x²(-4x+1)-2(3x-4).

Step-by-step explanation:
The Mathematical transformation of the given statement would be:
Answer:
(-6, 0).
Step-by-step explanation:
x^2 + 36y^2 + 12x = 0
Convert to standard form:
(x + 6)^2 - 36 +36y^2 = 0
(x + 6)^2 + 36y^2 = 36
Divide through by 36:
(x + 6)^2 / 36 + (y - 0)^2/ 36 = 1
Now compare this with the general form:
(x - h)^2/a^2 + (y - k)^2/ b^2 = 1
We see that the center (h, k) = (-6, 0).
Answer:
A=36
B=36
C=108
Step-by-step explanation:
A =B
2A+C=180
C is greater than A
2A+(A+72) =180
SIMPLIFY
3A +72=180
-72 ON BOTH SIDES
3A=108
DIVIDE BY 3
A=36
SO
B=36
36 TIMES 2 IS 72
180-72=108
SO
C=108
hope this helps
