Determine if the following triangle is a right triangle or not using the Pythagorean Theorem Converse. Triangle with side length

Nadusha1986 [10]

Answer:

It is a right triangle

Step-by-step explanation:

Information needed:

Formula: a^2+b^2= c^2

a: leg

b: leg

c: hypotenuse

the longest side is always the hypotenuse, so 17 in

the order of legs don't matter so 8 in and 15 in

Solve:

a^2+b^2= c^2

8^2+15^2= 17^2

64+225= 289

289= 289

Final answer:

It is a right triangle

What is 7 times the sum of a squared and b minus 4 times the sum of a squared and b

spayn [35]

The sum of a squared and b is given by
$a^2+b$

7 times the sum of a squared and b is given by
 $7(a^2+b)$
while 4 times the sum of a squared and b is given by
 $4(a^2+b)$

Therefore, 7 times the sum of a squared and b minus 4 times the sum of a squared and b is given by

$7(a^2+b)-4(a^2+b)=3(a^2+b)$
