Answer:

  256,096 ft²

Step-by-step explanation:

<u>Pyramid Area</u>

Each of the four faces is a triangle with a base of 756 feet and a height of 612 feet. The area of that triangle is ...

  A = 1/2bh

  A = 1/2(756 ft)(612 ft) = 231,336 ft²

The total area of the four visible faces of the Great Pyramid is ...

  pyramid area = 4 × 231,336 ft² = 925,344 ft²

__

<u>WTC Area</u>

Each of the four rectangular side faces of the WTC tower has a base length of 208 ft and a height of 1368 ft. The area of it is ...

  A = LW = (208 ft)(1368 ft) = 284,544 ft²

The area of the square top of the tower has an area that is ...

  A = s² = (208 ft)² = 43,264 ft²

The total area of the four visible sides and the top is ...

  WTC tower area = 4 × 284,544 ft² +43,264 ft² = 1,181,440 ft²

__

The difference between the areas is ...

  WTC tower area - Great Pyramid area =

     1,181,440 ft² -925,344 ft² = 256,096 ft²

The difference in visible area is 256,096 ft².

3q+4+9=-14 <br> what is Q
BlackZzzverrR [31]

Hi! Your answer is q = -9

Please see an explanation for a better and clear understanding to your problem.

Any questions about my answer and explanation can be asked through comments! :)

Step-by-step explanation:

Since we want to solve for q-term. That means we are going to isolate q-term.

\huge{3q+4+9=-14}

We can add 4 and 9 together.

\huge{3q+13=-14}

Because we want to know the value of q. That means we have to isolate q-term by subtracting both sides by 13.

\huge{3q+13-13=-14-13}\\\huge{3q=-27}

We are reaching to the final step where we divide the whole equation by 3.

\huge{\frac{3q}{3}=-\frac{27}{3}}\\\huge{q=-9}

Finally, the solution for this equation is q = -9. But what if you are not certain or sure about the answer? Let's check it out!

To check the answer, simply substitute q = -9 in the equation.

\huge{3q+4+9=-14}\\\huge{3(-9)+13=-14}\\\huge{-27+13=-14}\\\huge{-14=-14}

Notice that the equation is true for q = -9. Hence, we can conclude that the solution for this equation is q = -9.

Hope this helps!

Solve for a 4/a+4= -1/a+9
Karolina [17]

Answer:

a = -8

Step-by-step explanation:

4/a + 4 = -1/a + 9

-1(a + 4) = 4(a + 9)

-1a - 4 = 4a + 36

-5a - 4 = 36

-5a = 40

a = -8
