You'd multiply 8 by 4 to get 32, and then add 2 to get 34, which is the mans age. I hope this helps!

Answer:  The man is 34 years old.

Step-by-step explanation:  Given that a man's age is two years more than four times his son's age and his son is 8 years old now.

We are to find the age of the man.

Let x and y represents the age of the man and his son respectively.

Then, according to the given information, we have

x=4\times y+2\\\\\Rightarrow x=4y+2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

and

y=8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)

Substituting the value of y from equation (ii) in equation (i),we get

x\\\\=4y+2\\\\=4\times8+2\\\\=32+2\\\\=34.

Thus, the man is 34 years old.

A triangle has side lengths of 15 10 and 7 is it a right triangle
lions [1.4K]

Answer:

No, it is not a right triangle.

Step-by-step explanation:

Given:

The sides of the triangle =  15 10 and 7

To Find:

Whether the triangle is a right triangle = ?

Solution:

According to Pythagorean theorem , In an right triangle the the sum of the squares of the two smaller sides must equal to the square of the larger side

a^2 +b^2 =c^2\\

where

a and b are the smaller sides

c is the larger side

Now from the given data, lets assume

a = 10 and b =7 and c =15

Substituting in the above equation we get,

(10)^2 +(7)^2 = (15)^2

100 + 49 = 225

149 = 225

149 \neq 225

So, the given triangle is not a right triangle.
