What is the surface area of the figure? Can you please explain how to get it
goldenfox [79]

Answer:

The surface area of the solid = 582 feet²

Step-by-step explanation:

* At first lets study the solid

- it consists of 8 faces

- One base with dimensions 15 and 4 feet (1)

- Two side faces L-shaped with dimensions 15 , 4 , 9 ad 6 feet (2)

- One side face with dimensions 4 and 15 feet (3)

- One side face with dimensions 9 and 4 feet (4)

- One side face with dimensions 6 and 4 feet (5)

- One top base with dimensions 9 and 4 feet (6)

- One top base with dimensions 6 and 4 feet (7)

* Now lets find the area of the faces

- A(1) = 15 × 4 = 60 feet² ⇒ rectangular face

* We can find the area of L-shaped by this way

∵ Area of the square face = 15 × 15 = 225 feet²

∵ Area of the small rectangle = 9 × (15 - 9) = 54 feet²

- Lets subtract the area of the small rectangle from the area of

  the square, to find the area of the L-shaped

- A(2) = 2 ( 225 - 54) = 2 (171) = 342 feet²

- A(3) = 4 × 15 = 60 feet² ⇒ rectangular face

- A(4) = 9 × 4 = 36 feet² ⇒ rectangular face

- A(5) = 6 × 4 = 24 feet² ⇒ rectangular face

- A(6) = 9 × 4 = 36 feet² ⇒ rectangular face

- A(7) = 6 × 4 = 24 feet² ⇒ rectangular face

* Lets add all of these areas to find the surface area of the solid

∴ The S.A = 60 + 342 + 60 + 36 + 24 + 36 + 24 = 582 feet²

Gary is 25 years old. That is 7 more than
SpyIntel [72]

Answer:

2<em>x </em>+ 7 = 25

<em>x </em>= 7

Step-by-step explanation:

Gary: 25

Sean: <em>x</em>

----------------------------

Let's break down the sentence into mathematical terms

Gary <u>is</u> 25 years old. That <u>is</u> 7 more than twice <u>Sean's age.</u>

In math, is means equal to. It is represented with an equal sign (=)

Gary = 25. 25 = 7 more than twice <u>Sean's age.</u>

7 more is represented by 7 +

Gary = 25. 25 = 7 + than twice <u>Sean's age.</u>

Twice means double which is 2 ·

Gary = 25. 25 = 7 + 2 · <u>Sean's Age</u>

<u>Sean's Age</u> will be represented by <em>x</em>

Gary = 25. 25 = 7 + 2<em>x</em>

We don't need it to say<em> "Gary = 25" </em>in our equation.

25 = 7 + 2<em>x</em>

Let's rewrite it with the associative property.

2<em>x </em>+ 7 = 25

---------------------

Now, solve

2<em>x </em>+ 7 = 25

<em>-7           -7</em>

2<em>x</em> = 18

<em>÷</em><em>2  </em><em>÷</em><em>2</em>

<em>x </em>= 7

----------------------

Sean is 7 years old.
