Answer: The answer is 1,600.
Explanation: since her back yard is a square that means it has 4 sides, and her yard is 400 sq ft. So you multiply 400 by 4 which equals 1,600. I haven’t done this in a long time so I’m not positive. But that should be it.
Answer:
X=5
Step-by-step explanation:
4/3-1/3=1
1 / 1/5x = 5
The answer is C, because to find IQR you have to find the difference (subtract) of the first and third quartile
Answer:
a=-3
Step-by-step explanation:
Add the 2 from the left to the right, swapping the sign go be positive over the equal sign.
You then have a+3=0
Subtract the three from both sides:
a=-3
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).
