which expression is equivalent to m-4/m+4 + (m+2) ?

A. m-4/(m+4)(m+2)

B. (m+4)(m+2)/m-4

C. m-4)(m+2)/m+4

D. m+4/(m-4)(m+2)

**Answer:**

C.

**Step-by-step explanation:**

......................

The** expression** that is equivalent to the expression **(m - 4)/(m + 4) + (m + 2)** is {m + m² + 6m + 4}/{m + 4}.

An** expression **in mathematics is a combination of terms both constant and variable. For example, we can write the** expressions** as -

2x + 3y + 5

2z + y

x + 3y

Given is to find the **expression** is equivalent to -

(m - 4)/(m + 4) + (m + 2)

We have the following expression as -

(m - 4)/(m + 4) + (m + 2)

{(m - 4) + (m + 2)(m + 4)}/(m + 4)

{(m - 4) + m² + 4m + 2m + 8}/(m + 4)

{m + m² + 6m + 4}/{m + 4}

Therefore, the** expression** that is equivalent to the expression **(m - 4)/(m + 4) + (m + 2)** is {m + m² + 6m + 4}/{m + 4}.

At a bird sanctuary, the population of bluebirds is 120 and is increasing 4% annually. How many bluebirds will there be in 8 years?

The answer is: 158 birds

4% of 120 is 4.8 birds. So the population is increasing by 4.8 each year. 4.8 x 8 years = 38.4

120 + 38.4 = 158.4

4% of 120 is 4.8 birds. So the population is increasing by 4.8 each year. 4.8 x 8 years = 38.4

120 + 38.4 = 158.4

Myles has a room that is 300 m². If he wants to tile the room using 5 cm x 5 cm tiles, how many whole tiles will he have to use?

**Answer:**

Number of whole tiles need = 120,000 tiles

**Step-by-step explanation:**

**Given:**

Area of room = 300 m²

Dimension of each tile = 5cm x 5cm

**Find:**

Number of whole tiles need

**Computation:**

Dimension of tile in meter = 5 /100 = 0.05 m

Area of each tile = 0.05 x 0.05

Area of each tile = 0.0025 m²

Number of whole tiles need = Area of room / Area of each tile

Number of whole tiles need = 300 / 0.0025

**Number of whole tiles need = 120,000 tiles**

Total 120,000 tiles need to cover 300 m² room.

Jim takes out a mortgage for 30 years at an interest rate of 2.49% and his monthly repayments are $986.50. What is the principal loan amount? Round your answer to the nearest ten thousand dollars. Do NOT round until you have calculated the final answer.

**Answer:**

250000

**Step-by-step explanation:**

P=986.50(1-(1+.0249/12)^-(12)(30) Then divide the answer you get by (.0249/12)

**Answer: 250,000**

**Step-by-step explanation:**

If a dozen dozen candies cost a half-a-dozen dimes a dozen, how much will a half-a-dozen dozen candies cost?

**Answer:**

74

**Step-by-step explanation:**

The **cost **of **half-a-dozeon dozen candies **for this case will be $3.6

A **dozen **of a thing means 12 of such thing is in consideration. If we say we have a **dozen pencils**, then twe mean we have 12 **pencils**.

For this case, it is given that:

Cost of aA **dozen **contains 12 **quantities**.

A **dozen **dozen **candies **means 12 times 12 = 144 **candies**

half a **dozen ***dimes** *dozen cost = (12/2) × 12 dimes = 72 dimes

That means:

144 candies cost 72 dimes.

**Dividing **both **quantities **by 144 to get price of 1 candy:

144/144 = 1 candy's price = 72/144 dimes = 0.5 dimes = 0.05 dollars (1 dime = 0.1 dollars)

Half a dozen times dozen **candies **= 72 candies

1 **candy costs **0.05 dollars

72 **candies **cost [tex]72 \times 0.05 = 3.6[/tex] dollars.

Thus, the **cost **of **half-a-dozeon dozen candies **for this case will be $3.6

Is this for a Trig class? just wondering

**Step-by-step explanation:**

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

we want to find the Hypotenuse (Hyp) and are given an angle and the adjacent side (adj) sooo use CAH , b/c it has all of the pieces

Cos(37) = Adj / Hyp

Cos(37) = 11 / Hyp

swap Cos(37) and Hyp... an algebra trick you should know from college algebra or where ever you learned algebra

Hyp = 11 / Cos(37)

the measures of a triangle are in the ratio 2:3:5. what are the measures of the angles?

(give all 3 angle measurements pls)

9514 1404 393

**Answer:**

36°, 54°, 90°

**Step-by-step explanation:**

We have to assume that the given measures are *angle* ratios, not *side* ratios. Sides in the ratios 2:3:5 will not form a triangle.

For some multiplier x, the angle values will total 180°.

2x +3x +5x = 180

x = 180/(2+3+5) = 18

Then the angle measures are ...

2x° = 2·18° = 36°

3x° = 3·18° = 54°

5x° = 5·18° = 90°

**The angle measures are 36°, 54°, and 90°**.
