g(3) = 5(3) - 9

= 15 - 9 = 6

Answer : g(3) = 6

In the function [tex]g(x) =5x-9[/tex], the value of g(3) is equal to 6.

Given the following function:

To determine the value of g(3):

In this exercise, you're required to find the value of the given function when g of x is equal to 3.

Therefore, we would substitute the value of x into the given function.

Substituting the value of x into the function, we have:

[tex]g(x) =5x-9\\\\g(3) =5(3)-9\\\\g(3) =15-9\\\\g(3) =6[/tex]

g(3) = 6

The surface area of the rectangular prism with dimensions [tex]2[/tex] cm by [tex]2[/tex]cm by [tex]5[/tex] cm is [tex]48 cm^2.[/tex]

The surface area of a rectangular prism is [tex]2(lw+wh+lh)[/tex], where [tex]l[/tex] is length, [tex]w[/tex] is width, and [tex]h[/tex] is height.

A rectangular prism has dimensions of [tex]2[/tex] cm by [tex]2[/tex] cm by [tex]5[/tex] cm.

Let [tex]l=2[/tex] cm, [tex]w=2[/tex] cm and [tex]h=5[/tex] cm.

So, surface area [tex]= 2(lw+wh+lh)[/tex]

[tex]= 2 (2 \times 2 + 2 \times 5 + 2 \times 5)[/tex]

[tex]= 2 (4 + 10 + 10)[/tex]

-54.625 or -54 5/8

Step-by-step explanation:

4[tex]\frac{3}{4}[/tex] (-11.5) = -54.625 or -54 5-8

Let's set W as the width of the room and L as the length of the den. We know that the den is 10 ft longer than it is wide so that means:

W + 10 = L

Let's call this equation 1.

So also know that the area of the den is 144 ft2. Knowing that the equation for the area of a square is W x L, we know that for this den:

W x L = 144

Let's call this equation 2.

So now we have 2 equations and 2 unknowns. Let's take equation 1 and solve for W:

W = L - 10

Now we can substitute this value into equation 2.

(L - 10) x L = 144

L2 - 10L = 144

This looks very close to a quadratic equation. In fact, if we subtract 144 from both sides, we get the quadratic equation of:

L2 - 10L - 144 = 0

Now we can factor this equation into:

(L+8)(L-18) = 0

That means the two answers for L are -8 ft and 18 ft.

We can now substitute these values for L into equation 1 to solve for W.

W = L - 10

W = 18 - 10 or W = -8 - 10

So our 2 values for W are 8 ft and -18 ft.

Let's just make sure we did this correctly. We know that the area is 144 so (-8*-18) and (18*8) should equal 144 and it does! That means we did it correctly. Give that a den exists, it does not make sense that it has negative values, so the one real answer for this problem is that the width is 8 ft and the length is 18 ft.

The dimensions of the room were 16 feet wide and 22 feet long.

Given that Ed's den is 6 feet longer than it is wide, to determine if the den's area is 352 square feet, what are the dimensions of the room, the following calculation must be performed:

Therefore, the dimensions of the room were 16 feet wide and 22 feet long.

Answer:

Look at the proof down

Step-by-step explanation:

The given is;

→ ∠1 and ∠2 form a linear pair

→ ∠1 ≅ ∠3

We want to prove;

→ ∠2 and ∠3 are supplementary

We will write the proof in like a table

1. ∠1 and ∠2 formed a linear pair  ⇒  1. Given

2. m∠1 + m∠2 = 180°  ⇒ 2. Sum of angles on a straight line

3. ∠1 and ∠2 are supplementary angles  ⇒  3. Supplementary angles add up to 180°

4. ∠1 ≅ ∠3  ⇒  4. Given

5. m∠2 + m∠3 = 180°  ⇒  5. Substitution method

6. ∠3 is a supplement of ∠2  ⇒  6. Supplement of equal angles

7. ∠2 and ∠3 are supplementary  ⇒  7. Proved

Answer:

122

Step-by-step explanation:

1.8 times 50 is 90, and 90 plus 32 is 122

So, here we have the following equation... [tex]>See\;Below<[/tex]

[tex]1.8c+32[/tex]

We know that [tex]C=50[/tex] so the equation changes too the following... [tex]>See\;Below<[/tex]

[tex]1.8(50)+32[/tex]

So, lets remove the unneeded parentheses and add a multiplication sign [tex](*)[/tex]

[tex]1.8x50+32[/tex]

So, [tex]1.8*50=90[/tex] and [tex]90+32=122.[/tex]

So, [tex]122[/tex] is your final answer!
