Answer:

The roots of the equation are

Step-by-step explanation:

First rewrite the expression

That's

x² - 16

16 = 4²

So we have

x² - 4² = 0

Using the identity

Rewrite the expression

So we have

x² - 4² = 0 is

( x + 4)( x - 4) = 0

x + 4 = 0 x - 4 = 0

x = - 4 x = 4

The roots of the equation are

- 4 and 4

Is (0,0) a solution to this system?

Anuta_ua [19.1K]

Answer:

option-B

Step-by-step explanation:

we are given system of inequality as

$y\leq x^2-4$

$y>2x-1$

now, we can check solution

At (0,0):

we can plug x=0 and y=0

and check inequality

$0\leq 0^2-4$

$0\leq -4$

so, this is FALSE

now, we can check second inequality

$0>2\times 0-1$

$0>-1$

So, this is TRUE

so, option-B

Answer:

5 cm

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

V = lbh ( l is length, b is breadth and h is height )

Here l = 20, h = 12, V = 1200 and b is to be found, thus

20 × b × 12 = 1200, that is

240b = 1200 ( divide both sides by 240 )

b = 5
