Answer:

(Since 3.14 seems more reliable, I'll use that for all four instead)

A: 17.6 ft

B: 81.6 mm

C: 9 cm

D: 12 in

Step-by-step explanation:

$2(2.8)*3.14\\5.6 * 3.14\\17.584 approx. = 17.6$

$2(13)*3.14\\26 * 3.14\\81.64 approx. = 81.6$

$\frac{56.5}{6.28}=\frac{2825}{314}=8\frac{313}{314}approx. = 9$

$\frac{75.4}{6.28}=\frac{1885}{157}=12\frac{1}{157}approx. = 12$

A jewelry box has a volume of 14 cubic inches.The area of the base is 8 square inches. what is the height

AlekseyPX

The height of the jewelry box is 1.75. because the equation of a rectangular prism is V=Bh. so we already know the volume and the base so you just divide them and you get your height.

Factor the given quadratic function x2 + 9x = 36.

Gennadij [26K]

Answer:

(x + 12)(x - 3)

Step-by-step explanation:

${x}^{2} + 9x = 36 \\ {x}^{2} + 9x - 36 = 0 \\ {x}^{2} + 12x - 3x - 36 = 0 \\ x(x + 12) - 3(x + 12) = 0 \\ (x + 12)(x - 3) = 0$
