The sand makes up a rectangular prism of dimensions 8' by 10' by 0.5'.

The volume of sand is then V = L*W*H, or V = (10')(8')(0.5') = 40 cubic ft.

Select the solution(s) of log2x=1−log(x+4).

mart [117]

Step-by-step explanation:

log2x = 1 - log(x+4)

log2x = log10 - log(x+4)

log2x = log[10/(x+4)]

2x = 10/(x+4)

2x(x+4) = 10

2x² + 8x - 10 = 0

÷2 both sides of equation

x² + 4x - 5 = 0

(x+5)(x-1) = 0

x = -5, 1

x isn't be -5 because logA, A need to be > 0

So, x value is 1

Given quadrilateral TUVX ~ quadrilateral MNOP and VX = 5, XT = 10, and OP = 7, what is PM?

Likurg_2 [28]

$\dfrac{\overline{PM}}{\overline{OP}}=\dfrac{\overline{XT}}{\overline{VX}}\\\\
\dfrac{\overline{PM}}{7}=\dfrac{10}{5}\\\\
\dfrac{\overline{PM}}{7}=2\\\\
\overline{PM}=14$
