Answer:

D. 144

Step-by-step explanation:

find the volume of the shipping container and divide it by the volume of a box.

$2\frac{2}{3}$ × $1$ × $2$ = $\frac{16}{3}$

$\frac{1}{3}$ × $\frac{1}{3}$ × $\frac{1}{3}$ = $\frac{1}{27}$

$\frac{16}{3}$ divided by $\frac{1}{27}$ is 144.

Which side lengths form a right triangle? Choose all answers that apply: Choose all answers that apply: (Choice A) A 3, 6, \sqrt

dlinn [17]

Answer:

A, B and C

Step-by-step explanation:

Given any three side lengths of a right triangle, the longest side is the hypotenuse.

The side lengths of a right triangle must satisfy the Pythagorean Theorem.

Pythagorean Theorem: $Hypotenuse^2=Opposite^2+Adjacent^2$

Option A: $3, 6, \sqrt{45}$

$(\sqrt{45})^2=3^2+6^2\\45=36+9\\45=45$

True

Option B: 2.5, 6, 6.5

$6.5^2=6^2+2.5^2\\42.25=36+6.25\\42.25=42.25 (TRUE)$

Option C: $4, 8, \sqrt{80}$

$4, 8, \sqrt{80}\\( \sqrt{80})^2=4^2+8^2\\80=16+64\\80=80 (TRUE)$

Since all are true, the side lengths in Options A, B and C forms a right triangle,

PLEASE HELP MEEEEE!!!!!!!!!!! Solve this quadratic equation. x 2 + 5x + 3 = 0

andreev551 [17]

Answer:

$x1=\frac{-5+\sqrt{13}}{2}\\ \\x2=\frac{-5-\sqrt{13}}{2}$

Step-by-step explanation:

x² + 5x + 3 = 0

x = (- 5 +/- √5² - 4x1x3)/2x1

= (-5+/-√13)/2

x₁ = (- 5 + √13)/2

x² = (- 5 - √13)/2
