Answer:

86.20 ft²

Step-by-step explanation:

Hi there !

A = A₁ + A₂

A₁ =semicircle

A₁ = πr²/2

r = d/2 = 6.4ft/2 = 3.2 ft

A₁ = 3.14×(3.2ft)²/2 ≈ 32.15 ft²

A₂ = trapezium

A₂ = (b + B)×h/2

A₂ = (5.1ft + 6.4ft)×9.4ft/2 = 54.05 ft²

A = 32.15 ft² + 54.05 ft² = 86.20 ft²

Good luck !

Set up a ratio:

4 gallons / 30 plants = X gallons / 45 plants

Cross multiply:

4 * 45 = 30 * x

180 = 30x

Divide both sides by 30:

x = 180 / 30

x = 6

It would take 6 gallons.

galben [10]

Answer:

$2x^{2}$

Step-by-step explanation:

Find the GCF of the numbers 48, 6 and 26.

The largest number each can be divided by is 2, which is the GCF.

Find the GCF of $x^{2}, x^{3}, x^{6}$

The GCF is always the smallest exponent, so $x^{2}$ is the GCF

Combine the two GCF for the answer

$2x^{2}$
