A square pyramid has a height of 6 units and a volume of 70 units3. If a square prism has the same base area and volume as the s
Svetach [21]

Answer:

The height of the prism is h=2\ units

Step-by-step explanation:

step 1

Find the area of the base of the pyramid

The volume of the pyramid is equal to

V=\frac{1}{3}Bh

where

B is the area of the base of pyramid

h is the height of the pyramid

we have

V=70\ units^{3}

h=6\ units^{3}

substitute and solve for B

70=\frac{1}{3}B(6)

70=2B

B=35\ units^{2}

step 2

Find the height of the prism

The volume of the prism is equal to

V=Bh

where

B is the area of the base of prism

h is the height of the prism

we have

V=70\ units^{3}

B=35\ units^{2}

substitute and solve for h

70=35h

h=2\ units

What is the missing coefficient?
Afina-wow [57]

For this case we have the following expression:

(15x ^ 2 + 11y ^ 2 + 8x) - (7x ^ 2 + 5y ^ 2 + 2x) =

We eliminate the parentheses taking into account that:

- * + = -\\15x ^ 2 + 11y ^ 2 + 8x-7x ^ 2-5y ^ 2-2x

We add similar terms:

15x ^ 2-7x ^ 2 + 11y ^ 2-5y ^ 2 + 8x-2x =

Different signs are subtracted and the sign of the major is placed:

8x ^ 2 + 6y ^ 2 + 6x

Finally, the expression is reduced to:

8x ^ 2 + 6y ^ 2 + 6x

Answer:

8x ^ 2 + 6y ^ 2 + 6x

Option B
