The area is 24² because 8*3 is 24
The perimeter is 8+8+3+3 which is 16+6 and that equals 22
22 is the Perimeter and the Area is 24²

Answer:

$\huge\boxed{\sf x = 1.8}$

Step-by-step explanation:

$\sf 2x-1.5 = 2.1\\\\Add \ 1.5 \ to \ both \ sides\\\\2x = 2.1 + 1.5\\\\2x = 3.6\\\\Divide \ 2 \ to \ both \ sides\\\\x = 3.6 / 2\\\\x = 1.8\\\\\rule[225]{225}{2}$

Hope this helped!

Which values from this set {−12, −9, −3, 0, 3, 6} satisfy this inequality?

Vesna [10]

The values -3, -9 and -12 satisfy the inequality.

In this question we evaluate each element of the set to determine whether value belongs to the inequation given on statement:

x = 0

$-13\cdot 0 + 3 \ge 6$

$3\ge 6$ (FALSE)

x= -3

$-13\cdot (-3) +3 \ge 6$

$42\ge 6$ (TRUE)

x = -9

$-13\cdot (-9)+3 \ge 6$

$120\ge 3$ (TRUE)

x = -12

$-13\cdot (-12) +3 \ge 6$

$159 \ge 6$ (TRUE)

The values -3, -9 and -12 satisfy the inequality.

The volumes of two similar solids are 729 inches3 and 125 inches3. If the surface area of the smaller solid is 74. 32 inches2, w

The surface area of the larger solid, rounded to the nearest hundredth is given by: Option B: $240.80\: \rm inch^2$

<h3>How can we interpret volume of a solid?</h3>

Volume of a solid is usually expressed in cubic units, or units cube.

Suppose that the volume was expressed in x cubic units. Then you can say that the considered solid takes same space as the volume occupied by x cubes of 1 unit as their side lengths.

<h3>What are similar objects?</h3>

They're like zoomed version of each other(might be non-zoomed, zoomed in, or zoomed out). Their sides can be obtained by multiplying one object's sides by a single constant(by single constant, we mean constant which will be same for obtaining any corresponding side).

For the given case, we're given that:

Volume of first solid = 729 cubic inches.
Volume of second solid = 125 cubic inches.

Both solids are similar.

Thus, let the scale factor by which their sides change be 'f'.

Then, we get:

Side of first solid = f × side of second solid

Surface area of first solid(a square piece chosen on its surface) = f × f × surface area of second solid

(as two times sides multiplied, so two times f got multiplied).

Similarly,

volume of first solid = f × f × f × volume of second solid.

Or

$729 = f^3 \times 125\\f = \: ^3\sqrt{\dfrac{729}{125}} = \dfrac{9}{5} = 1.8$

As surface area of smaller solid(second solid is smaller as its volume is less) is 74.32 sq. inches, and f = 1.8, thus, we get:

$S_{\text{larger solid}} = f^2 \times S_{\text{smaller solid}} = (1.8)^2 \times 74.32\\S_{\text{larger solid}} = 240.7968 \approx 240.80 \: \rm inch^3$

Thus, the surface area of the larger solid, rounded to the nearest hundredth is given by: Option B: $240.80\: \rm inch^2$
