Find the height in inches of a wall that is 6 inches less than 12 feet tall.

Gre4nikov [31]

Answer: I believe its 138 inches, if 'wrong i'm sowwy.

Step-by-step explanation: It sates to find the height of the was 6 inches less than 12 feet tall, this means were subtracting 6 (less than) into 12 feet. We cant do that until we convert inches into feet. we know that 12 inches is equal to 1 foot.

Easier way to do this is to .. multiply 12 by 12 which is = 144

12 inch = 1 ft

24 inch = 2 ft

SO, 144 - 6 = 138

To convert this into feet we divide 12 into 138 which is 11.5 feet.

Please help! Find the missing

Veronika [31]

Answer:

x = 13

Step-by-step explanation:

Here, we want to get the missing side

from what we have, the triangle is a right angled triangle

In this kind of triangle, the Pythagoras’ theorem works

The square of the side facing the right angle ( marked x here) is equal to the sum of the squares of the two other sides

We have this as;

x^2 = 5^2 + 12^2

x^2 = 25 + 144

x^2 = 169

x = √169

x = 13

Simplify using distributive law ; 1.) X n ( X n Y ) 2.) ( X n Y ) u ( X n Y )

goblinko [34]

Answer:

X n Y , X n Y

Step-by-step explanation:

1) Use Associative law:

X n (X n Y) = (X n X) n Y

Idempotent law:

= X n Y

2) it is in the 'distributed' form, thus we need to reverse the distribution,

akin to 'factorization':

(X n Y) u (X n Y) = (X n (Y u Y))

which can be further simplified using idempotent law:

= X n Y
