Answer:
There is an 144 degree difference.
Step-by-step explanation:
112=(-32)+x
solve like a regular equation which will give you 144
(add 32 to 112)
Multiply 18 * 3 and 20 * 3
18*3 = 54
20 * 3 = 60
Length = 54 cm ; Width = 60 cm
Area = L x W
54 * 60 = 3240
Area = 3240 cm
Answer:
Step-by-step explanation:
Let us divide by 14 by 7 which is 2, so the equation is:
Let us multiple 21 over the other side since 21 is in the denominator of the equation, so we get
So the answer is 42.
3 x 3 - ( (-1)^2 - 2)^2
Start evaluating the one in the most inner bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1 - 2)^2
There is one more bracket, so we do what is in the bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1- 2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
Between x and -, we do the x first:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1- 2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1
Then we do the -:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1- 2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1
= 8
