Step-by-step explanation:
Answer:
The answer to your question is below
Step-by-step explanation:
3(3x + 2) + 5 - 4x = 5x + 7
Step 1: 3(3x + 2) + 5 - 4x There is no error here, only wrote the
polynomial again
Step 2: 9x + 2 + 5 - 4x He forgot to multiply 3 x 2 = 6
9x + 6 + 5 - 4x
Step 3: 9x - 4x + 2 + 5 He simplified like terms
Step 4: 5x + 7 but is incorrect due to his mistake
The right answer should be 5x + 11
104:91
8+7 is 15
195 divided by 15 is 13
13 times 8 is 104
13 times 7 is 91
Answer:
The altitudes of ΔTSP is SC is 8 unit ,
PA is 5
unit ,
TB is 5
unit .
Step-by-step explanation:
Given as :
The Triangle Δ TSP having side TS , SP , TP
The measure of TS = 12 cm
The measure of SP = 10 cm
The measure of TP = 10 cm
Let The altitude from point T on side PS = TB
The altitude from point S on side PT = SC
The altitude from point P on side TS = PA
The altitude divide the sides
TS = TA + AS
PS = PB + PS
PT = PC + CT
So, From Pythagoras theorem
PA² = PS² - AS²
PA² = 10² - 5²
Or, PA² = 100 - 25
Or, PA = 
∴ PA = 5
unit
Again
TB² = TS² - BS²
TB² = 10² - 5²
Or, TB² = 100 - 25
Or, TB = 
∴ TB = 5
unit
Similarly
SC² = TS² - TC²
SC² = 10² - 6²
Or, SC² = 100 - 36
Or, SC = 
∴ SC = 8 unit
Hence The altitudes of ΔTSP is SC is 8 unit , PA is 5
unit , TB is 5
unit . Answer
<h2>
Answer:</h2>
The total number of ways can first, second and third place can be assigned are:
6840
<h2>
Step-by-step explanation:</h2>
The total number of people that compete are: 20
Out of these 20 people we have to chose 3 people and also arrange them according to their ranks.
We know that when we have to choose and arrange r items out of total n items then we need to use the method of permutation.
Hence, the formula is given by:

Here we have:
n=20 and r=3
Hence, the number of ways first, second and third place can be assigned are:

Hence, the answer is:
6840
