Answer:

W = 6

L = 9

Step-by-step explanation:

area = 54 = L x W

L = W + 3

substitute for L:

54 = W(W + 3)

W² + 3W = 54

W² + 3W - 54 = 0

(W + 9)(W - 6) = 0

W = 6

L = 6 + 3 = 9

A cylinder with radius 3 feet and height 5 feet is shown.

Leviafan [203]

Answer:

The volume of the cylinder is <u>141.23 cubic feet </u>

Step by step explanation :

<u>Given</u>-

Radius of cylinder = 3 feet
Height of cylinder = 5 feet

Now, we know that

<h3> $\boxed {\mathfrak \red{ volume \: of \: cylinder = \pi {r}^{2} h}}$ </h3>

where, r is the radius of the cylinder & h is the height of the cylinder.

Now,

Volume of the cylinder = $\frac{22}{7} \times {3}^{2} \times 5$

$= \frac{22}{7} \times 3 \times 3 \times 5$

$= 141.428571$ ( approximately )

$= \boxed{ 141.43 \: \mathfrak { {ft}^{3}} }$

Ilia_Sergeevich [38]

Your answer is
${x}^{2} \div {2} {z}^{9}$
because the numbers raised to negative powers must be flipped over the divisor to become positive. Then, when multiplying 2 and z, you add their exponents.
