I believe your answer is the first option, 1/2 ft.

*Volume is expressed by length x width x height.

If we multiply the length 5/7 and the height 1 & 1/2 we get 15/14:

*To multiply fractions you must multiply across, multiply the numerator (or top number) by the numerator and the denominator (bottom number) by the denominator.

- Let's turn 1 & 1/2 into a mixed fraction to make things a little easier. 1 & 1/2 also equivalent to 3/2

-Multiply the numerators together, 5 from the 5/7 and now 3 from the 3/2
(5 x 3 = 15)

-Multiply the denominators together, 7 from the 5/7 and 2 from the 3/2
(7 x 2 = 14)

Therefore, 5/7 x 1 & 1/2 is 15/14.

Now what multiplied by 15/14 equals 15/28?

Well... 1 x 15 = 15. That gives us our numerator, 1.

2 x 14 = 28... and we have our denominator 2.

Putting those two together we get a fraction of 1/2. Your width is then 1/2 ft.

I'm so sorry for all the work here! I know it's a lot. I hope it's not too confusing to look at. Hopefully this helps!

Together, the area of the two bases is
(6 in)×(8 in) = 48 in²

The lateral area is the product of the height of the prism (2 in) and the perimeter of the base (6 in +8 in +10 in), so is
(2 in)×(24 in) = 48 in²

The total area is the sum of these
area = 48 in² +48 in² = 96 in² . . . . . . . . . matches the 3rd selection

Find the product.

4vir4ik [10]

Answer :

$6{y}^{4} {z}^{2} + 12 {y}^{3} {z}^{2}-3 {y}^{3} {z}+3 {y}^{2} {z}^{2}$

Step-by-step explanation :

To find the product of

$3 {y}^{2} z(2 {y}^{2} z + 4yz - y + z)$

First we expand the bracket ,

it implies that, we use the expression outside the bracket to multiply individual expressions inside the bracket.

Hence

$3 {y}^{2} z(2 {y}^{2} z + 4yz - y + z)$

$= 3 {y}^{2} z(2 {y}^{2} z) + 3 {y}^{2} z(4yz) - 3 {y}^{2} z(y )+3 {y}^{2} z( z)$

we now apply the law of indices

${a}^{m} \times {a}^{n} = {a}^{m+n}$

meaning, when you are multiplying two expressions with the same bases , repeat one of the bases and add the exponents.

Then, simplify to obtain

$= 6{y}^{4} {z}^{2} + 12 {y}^{3} {z}^{2}-3{y}^{3} {z}+3 {y}^{2} {z}^{2}$
