Step-by-step explanation:
The formula for the area of a square is:
A
=
s
2
Where:
A
is the area of the square.
s
is the length of the side of a square.
Substituting and solving for
s
gives:
225
cm
2
=
s
2
We can take the square root of each side of the equation giving:
√
225
cm
2
=
√
s
2
15
cm
=
s
s
=
15
cm
The formula for the perimeter of a square is:
p
=
4
s
Where:
p
is the perimeter of the square.
s
is the length of the side of a square.
Substituting for
s
from the solution for the previous formula and calculating
p
gives:
p
=
4

Answer: x=18, R=20 degrees,
sin Q=3/5
cos Q=4/5
tan Q=3/4
sec Q=5/4
csc Q=5/3
cot Q=4/3
Step-by-step explanation:
Distance formula: a^2+b^2=c^2
30^2=24^2+x^2
900=576+x^2
x^2=324
x=18
180=P+Q+R
180=90+70+R
180=160+R
R=20 degrees
sin Q=18/30=3/5
cos Q=24/30=4/5
tan Q=18/24=3/4
sec Q=30/24=5/4
csc Q=30/18=5/3
cot Q=24/18=4/3
Answer:
$2.60
Step-by-step explanation:
$40.00 x 6.5% = $2.60
For this case we must multiply the following expression:
Applying distributive property we have:
By definition of multiplication of powers of the same base, we have to put the same base and add the exponents:
Adding similar terms:
Answer:
Answer:
-10 or 25 (read my explanation)
Step-by-step explanation:
(-5)2
-5*2=-10
(Unless the 2 is supposed to be an exponent)
If it is supposed to be an exponent the answer is 25
(-5)^2
25
