Answer:

24/3-4

Answer is 12

Step-by-step explanation:

To find the answer, you have to work backwards. You also have to use PEMDAS. Since she multiplied her answer to get 24, you have to work backwards and divide by 3 first. You will get the number 8 after that because 24/3 is 8. Since she also subtracted 4, you have to work backwards and add 4. That gives you an original number of 12.

Subtract.<br> (6-v-25) - (7+-4)

dmitriy555 [2]

Answer:

$\left(6-v-25\right)-\left(7+\left(-4\right)\right)=-v-22$

Step-by-step explanation:

Considering the expression

$\left(6-v-25\right)\:-\:\left(7+-4\right)$

$\left(6-v-25\right)-\left(7+\left(-4\right)\right)$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$6-v-25-\left(7-4\right)$

$\mathrm{Subtract\:the\:numbers:}\:7-4=3$

$6-v-25-3$

$\mathrm{Group\:like\:terms}$

$-v+6-25-3$

$\mathrm{Add/Subtract\:the\:numbers:}\:6-25-3=-22$

$-v-22$

Therefore,

$\left(6-v-25\right)-\left(7+\left(-4\right)\right)=-v-22$

Find the surface area of a hexagonal prism if the length of each side of the hexagonal base is 4 cm and the height is 7 cm.

olya-2409 [2.1K]

The surface area of a hexagonal prism willl be 251.13844 cm².

<h3>What is the surface area?</h3>

The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.

A=6ah+3√3a²

A=6×4×7+3√3×4²

A≈251.13844

Hence the surface area of a hexagonal prism willl be 251.13844 cm².
