Answer:
27 inches
Step-by-step explanation:
We are using the Pythagorean theorem
a^2 +b^2 = c^2 where c is the hypotenuse
We are given the diagonal, which is the hypotenuse and a leg
36^2 + b^2 = 45^2
Subtract 36^2 from each side
36^2 + b^2 - 36^2 = 45^2 - 36^2
b^2 = 45^2 - 36^2
b^2 =2025-1296
b^2 =729
Take the square root of each side
sqrt(b^2) = sqrt(729)
b =27
Answer:
- 12x² + 9x + 9
Step-by-step explanation:
(- 10x² + 2) + (- 2x² + 9x + 7 ) ← remove parenthesis
= - 10x² + 2 - 2x² + 9x + 7 ← collect like terms
= - 12x² + 9x + 9
Answer:
<h3>
present age of son = 10 </h3><h3>
present age of father = 40</h3>
Step-by-step explanation:
Let, present age of son be 'x'
present age of father be 'y'
y = 4x→ equation ( i )
After five years,
Son's age = x + 5
father's age = y + 5
According to Question,

Put the value of y from equation ( i )

Distribute 3 through the parentheses

Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S. and change its sign

Collect like terms

Calculate the difference

Now, put the value of X in equation ( i ) in order to find the present age of father

plug the value of X

Calculate the product

Therefore,
Present age of son = 10
present age of father = 40
Hope this helps..
