Is the expression x3•x3•x3 equivalent to x3•3•3? Why or why not? Explain your reasoning.

1 answer:

3 0

If the first expression reads x(cube) • x(cube) • x(cube) and x(cube • cube • cube), then the answer is no. They are not equal.

x(cube) • x(cube) • x(cube) will be equivalent to x(to the 9th power) while x(cube • cube • cube) will be equivalent to x( to the 27th power).

The width of a rectangle is 12 units. Can the perimeter x of the rectangle can be 60 units when its length y is 18 units? (1 poi

juin [17]

If the width is 12 and the length is 18, the perimeter of the rectangle is 12 + 12 + 18 + 18, or 60. So yes the perimeter can be 60.

What is the length of AB? 6units? , 12 units?, 10 units ?, 14 units?

Readme [11.4K]

Answer:

C. 10 units

Step-by-step explanation:

Use the distance formula:

$(x_{1},y_{1})\\\\(x_{2},y_{2})\\\\d=\sqrt{(x_{2}-x_{2})^2+(y_{2}-y_{1})^2}$

Find the coordinate points of A and B:

$A(-7,-6)\\\\\\B(1,0)$

Insert the values into the formula:

$d=\sqrt{(1-(-7))^2+(0-(-6))^2}$

Two negatives make a positive. Simplify:

$d=\sqrt{(1+7)^2+(0+6)^2}$

Simplify addition:

$d=\sqrt{(8)^2+(6)^2}$

Simplify exponents (x²=x·x):

$d=\sqrt{64+36}$

Simplify addition:

$d=\sqrt{100}$

Find the square root (x·x=√y):

$d=10$

The length of AB is 10 units.

(-3,-2) and (x,6); slope: -8/5

Sergio039 [100]

Answer:

$slope = \frac{6 - ( - 2)}{x - ( - 3)} \\ \frac{ - 8}{5} = \frac{6 + 2}{x + 3} \\ - 8(x + 3) = 5(6 + 2) \\ - 8x - 24 = 5(8) \\ - 8x - 24 = 40 \\ - 8x = 40 + 24 \\ \frac{ - 8x}{ - 8} = \frac{64}{ - 8} \\ x = - 8$
