Answer:

Prism

Step-by-step explanation:

A polygon is a plane figure connected by straight lines to form a closed shape, examples are triangle, square, hexagon, octagon e.t.c.

A prism is a solid figure that has two parallel and congruent faces (called the bases of the prism). The cross section of a prism parallel to the bases are the same shape as the bases. Prisms are being named according to the shape of the base polygon.

I need to know if the volume is 108 or 900

slega [8]

The answer is neither 108 or 900, but it is V = 1357.17

To solve, use the formula for the volume of a cone:
$\frac{ \pi r^2h}{3}$

fill r with 6 and h with 36

$\frac{ \pi (6)^2(36)}{3}$

When you solve that, you get 1357.17

What is the factored form of the expression?

Georgia [21]

Answer: The answer is (d) $(4x+7)(7x+8).$

Step-by-step explanation: Given equation to be factored is

$28x^2+81x+56.$

The given expression is quadratic, so we can factor it into two linear factors, by using the following factorisation rule.

$x^2+(a+b)x+ab=(x+a)(x+b).$

So, the given equation can be factorised using the above rule. The factorisation is as follows.

$28x^2+81x+56\\\\=28x^2+49x+32x+56\\\\=7x(4x+7)+8(4x+7)\\\\=(4x+7)(7x+8).$

Thus, the correct option is (d).

Find two numbers, if … b Their sum is −7 and their difference is 14

Delicious77 [7]

Answer:

x=0

y=-21/7

Step-by-step explanation:

Let the two unknown be x and y

x+y=-7...(1)

x-y=14...(2)

From (1) make x the subject of formula

x=-7-y...(3)

Substitute (3) into (2)

-7-y-y=14

-7-2y=14

Add 7 to both sides

-2y=21

Add both sides by-2

y=-21/2

Substitute the value of y into (3)

x=-7-(-21/2)

x=-7+21/3

Lcm

x=-21+21/3

x=0/3

x=0
