Answer:

x= 8 feet (answer : A)

Step-by-step explanation:

hello :

the perimeter is : P= 2(x+y) y : the length x : the width

P=40 and y = 12 calculate : x

2(x+12) =40

divid by 2 : x+12 =20

x=20-12

x= 8 feet

The surface area of prism 1 is 36 cm²

<h3>Calculating surface area</h3>

From the question, we are to calculate the surface area of prism 1

From the given information, we have that the two hexagon-based prism are similar

Since the shapes are similar, we can write that

(Length of a side in prism 1)² / (Length of the similar side in prism 2)² =

Area of prism 1 / Area of prism 2

From the given information,

Length of a side in prism 1 = 3 cm

Length of the similar side in prism 2 = 8 cm

Area of prism 2 = 256 cm²

Thus,

3² / 8² = Area of prism 1 / 256

Area of prism 1 = (256 × 3²)/ 8²

Area of prism 1 = (256 × 9)/ 64

Area of prism 1 = (2304)/ 64

Area of prism 1 = 36 cm²

Hence, the surface area of prism 1 is 36 cm²

Answer:

when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°.

Step-by-step Explanation:

The relationship between an intercepted arc and an inscribed angle is given as:

the measure of the intercepted arc = twice the inscribed angle that intercepts it.

Also, by virtue of this, when two inscribed angles intercepts the same arc, both inscribed angles are said to be congruent. And the measure of both angles equal the measure of the arc they both intercept.

Therefore, if the measure of an arc, that is intercepted by 2 inscribed angles, is given as 75°, both inscribed angles equal 75° as well. Thus, each of the inscribed angles is half the measure of the intercepted arc.

Therefore, the statement that is true about inscribed angles is: "when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°."

Answer:

$\sqrt[3]{432 {x}^{5} } \\ \\ 432 = 6 \times 6 \times 6 \times 2 = {6}^{3} \times 2 \\ {x}^{5} = x \times x \times x \times x \times x = {x}^{3} \times {x}^{2} \\ \\ \sqrt[3]{432 {x}^{5} } = 6x \sqrt[3]{2 {x}^{2} }$

I hope I helped you^_^
