In the first one you are missing (a +7) so it's going to be 9(a +7) or when you factor that out it will be 9a 63
In the other one you are missing the (a +5) so it's going to be 7a(a + 5) or when you factor it out it will be 7a2 + 35a
Step-by-step explanation:
a2+ 9a + 20 = (a + 4) (a + 5)
a2 + 11a+ 28 = ( a + 7) ( a + 4 )

B. (m+4)(m+2)/m-4
C. m-4)(m+2)/m+4
D. m+4/(m-4)(m+2)
Answers
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}.
What is algebraic expression?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}.

Mountain officials want to build a new ski lift from B to C, as shown in the figure below. The distance from A to C is 1540 feet. They measure angle DAC to be 38º and angle DBC to be 25º. What is the distance from A to B ? Round your answer to the nearest tenth of a foot.
Answers
Answer:
there is a 13 degree difference from DBC and DAC
with that you divide 1540 by 13 as you get that 118.461 feet
that means that there is a 118.461 difference from B to C and A to B
so the answer is either 1658.461ft or 1421.539ft I am not sure if that is correct or not but best of luck mate

Suppose 10 tosses of a coin were all heads, and you switch to a new coin. What is the probability of tossing this new coin and getting another head?
Answers
Answer:
50% or 1/2 Could be 100% but i think it is 50%
Step-by-step explanation:
Because Changing the coin will make no difference.
The probability of getting heads is same as the probability of tails which is [tex]\frac{1}{2}[/tex].
What is the probability?
The concept of probability is used to assign a numerical description to the likelihood of occurrence of an event.
Probability can be defined as the number of favorable outcomes divided by the total number of possible outcomes of an event.
Here given that,
The [tex]10[/tex] tosses of a coin were all heads, and you switch to a new coin.
So, the probability of getting all heads is [tex]2^{-n}[/tex]
And we have [tex]n=10[/tex],
Then, the probability of getting the heads is
[tex](^{n}C_k)(\frac{1}{2})^k(\frac{1}{2})^{n-k}=2^{-n}(^nC_k)[/tex]
Hence, the probability of getting heads is same as the probability of tails which is [tex]\frac{1}{2}[/tex].

If a dozen dozen candies cost a half-a-dozen dimes a dozen, how much will a half-a-dozen dozen candies cost?
Answers
Answer:
74
Step-by-step explanation:
The cost of half-a-dozeon dozen candies for this case will be $3.6
How much a dozen consists of ?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 a dozen dozen candies = half a dozen dimes a dozenCost of a half a dozen dozen candies = ? (to find)A 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

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?
Answers
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.
