Answer:
Options (2) and (5)
Step-by-step explanation:
Given in the question,
Length of OQ = 45
OP = (6x + 5)
PQ = 4x
By segment addition postulate,
Length of a segment OQ = length of segment OP + length of segment PQ
45 = 6x + 5 + 4x
10x + 5 = 45
10x = 45 - 5
10x = 40
x =
x = 4
Therefore, Option (2) and Option (5) are the correct options.
Answer:
No, it is incorrect.
Step-by-step explanation:
The quadratic equation is
or . To complete square we take the coefficient of x divided by 2, square that value and add the result to both sides. In the equation given the number to do the process is 20, not 6, then the solution method is incorect.
Answer:
NO it is not correct
Step-by-step explanation:
Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.
b. - 3/5 x 4
c. - 3/- 5 x 4
d. (- 3 x 4) / (- 3 x (-5))
Answer:
18 cans
Step-by-step explanation:
Given : 10 men can survive 24 days on 15 cans
To find : how many cans for 8 men can survive for 36 days
Solution : 1 men can survive 1 day on= 15/ 10×24 = 15/240 cans
8 men can survive 1 day = 8×15/240= 1/2 cans
8 men can survive for 36 days = 36/2= 18 cans
therefore, 8 men can survive for 36 days = 36/2= 18 cans
