Answer:
Present age of Juna = 10 years
Present age of Jubin = 16 years
Step-by-step explanation:
Ratio of present ages = 5: 8
Let the present ages of:
Juna be 5x years and Jubin be 8x years
(where x is the common multiplier of the given ratios)
Four years after:
Juna's age = (5x + 4) years
Jubin's age = (8x + 4) years
According to the question:
(5x + 4) + (8x + 4) = 34
13x + 8 = 34
13x = 34 - 8
13x = 26
x = 26/13
x = 2
5x = 5*2 = 10 years
8x = 8*2 = 16 years
Hence,
Present age of Juna = 10 years
Present age of Jubin = 16 years
The simplified form of the difference quotient of equation 
. in the form 9x + 9h + 5.
In question for equation , simplified to difference quotient in the form of Ax+Bh+C where A, B, C are integers
<h3>What is equation?</h3>
equation is the relationship between variable and represented as is example of polynomial equation.
We know that,
for difference quotient
While, compared with Ax+Bh+C
we have A=9, B=9, C=5.
Thus, The required value of difference Quotient in the form Ax+Bh+c where A, B and C is 9, 9 and 5 respectively

The answer is C.
Proof:
8×4-(2×3+8)÷2
=32-(6+8)÷2
=32-14÷2
=32-7
=25
Answer:
D.
Step-by-step explanation:
a² -b²= (a-b)(a+b)
100x²-49y²= (10x-7y)(10x+7y)
