Answer:

2nd choice: x=4 and x=-4

Step-by-step explanation:

x^2 - 16 = 0 can be simplified to (x-4)(x+4)=0

x-4 = 0 so x = 4

and x + 4 = 0 so x = -4

Find the next item in the sequence. 15, 30, 45, 60, ...

amid [387]

The rate of change is 15. We know this because 30 - 15 = 15, 45 - 30 = 15, and 60 - 45 = 15.

The next item in the sequence would be 75, since 60 + 15 = 75.

A triangle with sides of lengths 9, 22, and 24 is a right triangle

Leona [35]

Answer:

The statement is false

Step-by-step explanation:

we know that

if the triangle is a right triangle

then

the triangle must satisfy the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$

we have

$c=24\ units$

$a=9\ units$

$b=22\ units$

substitute

$24^{2}=9^{2}+22^{2}$

$576=81+484$

$576 \neq 565$

therefore

Is not a right triangle

The statement is false
