A rectangular prism has a height of 4 meters, a surface area of 96 square meters, and a base area of 8 square meters. Calculate
tatyana61 [14]
The perimeter is 56m

H = 4m
Base area =  96m^2

96/4 = 24
Therefore the length is 24m

4m + 24 = 28m
multiplied by 2 is equal to 56m.

Select the correct answer. A new building in the shape of a square pyramid is to be constructed. The slant height will be five t
marysya [2.9K]

From the information given about the square pyramid, the maximum base length of the building is 67.42 cm.

<h3>How do you determine the maximum side length?</h3>

We are given the following  details  are:

Base = b

Slant height (l) = 5b

The lateral surface area is calculated using:

L = 2bl

So, we have:

L = 2 * b * 5b

Evaluate the product

L = 10b²

The total surface area is calculated using:

T = L + b²

So, we have:

T = 10b² + b²

Evaluate the sum

T = 11b²

Recall that the maximum surface area is 50,000 square feet

So, we have:

11b² = 50000

Divide both sides by 11

b² = 50000/11

Taking the square root of both sides, we have

b = 67.42

Hence, the maximum base length of the building is 67.42 cm

If f ( x ) = 3x² - 5x + 7 , Show that f ( -1 ) = 3 f ( 1 ) .<br><br><br><br><br>Tysm :')​
Lelechka [254]

Solution :

  • 3x² - 5x + 7

put x = -1

  • 3(-1)² - 5(-1) + 7

  • 3(1) + 5 + 7

  • 3 + 12

  • 15

Now, put x = 1

  • 3(1)² - 5(1) + 7

  • 3(1) - 5 + 7

  • 3 + 2

  • 5

here :

  • f(-1) = 15

  • f(-1) = 3(5)

  • f(-1) = 3 f(1)
