the picture in the attached figure
we know that
area of the triangle is equal to

in this problem
A=47 in²
b=x
h=x
so

therefore
the answer is
x=9.7 in
Zero.
Anything times zero is zero.
-20 * -10 = 200
200 * -1 = -200
-200 * 0 = 0
Answer:
21
Step-by-step explanation:
Three raise to third power can be written as
. In this three is the base which is raised to third power.

Next we need to subtract 6 from Three raise to third power(i.e from 27)
which can be written mathematically as

Hence 6 less than three raised to the third power is 21 as explained above.
Answer:
There will be 128 holes
Step-by-step explanation:
Simply think of each fold as doubling the number of holes. So since we have 6 folds, that will be 2^6 and then we have 2 holes in those folds, which makes 2*2^6 == 2^7 == 128 holes. Cheers.
8x4=32
32+40=72
72/2=36
36+6=42
The number is 42
