How do I solve for X?

lidiya [134]

We use the theory of Pythagoras because the triangle is right.

$AB {}^{2} = AC {}^{2} + BC {}^{2}$
since AB = AC = x
$8 {}^{2} = x {}^{2} + x {}^{2}$
$64 = 2x {}^{2}$
$32 = x {}^{2}$
$x = \sqrt{32}$
$x = \sqrt{16 } \times \sqrt{2}$
$x = 4 \sqrt{2}$

To find the product of 42.12 and 10³, move the decimal point in 42.12 __ places to the right because 10³ has __ zeros.

docker41 [41]

Answer:

Both answers are 3.

Step-by-step explanation:

10^3 = 10 * 10 * 10 = 1000

When you multiply 42.12 by 10^3, you are multiplying 42.12 by 1000.

When you multiply a number by a power of 10, such as 10, 100, 1000, etc., move the decimal point of the number to the right the same number of places as the number of zeros in the power of 10.

42.12 * 1000 = 42,120
