Answer:
Step-by-step explanation:
The sum of the two costs is $52, so we can write ...
x + y = 52
The shoes cost $4 more than the jacket, so we can write ...
x - y = 4
These are your system of equations.
__
Subtract the second equation from the first:
(x +y) -(x -y) = (52) -(4)
2y = 48 . . . . . simplify
y = 24 . . . . . . .divide by 2
The cost of the jacket is $24.
<h3>I'll teach you how to solve (sqrt 9)^2 +5</h3>
-------------------------------------------------
(sqrt 9)^2 +5
Apply radical rule:
(9^1/2)2
Apply exponent rule:
9^1/2*2
1/2* 2= 1
=9
9+5= 14

Answer: 9a^4 - b^2
= (3a^2)^2 - b^2
= (3a^2 + b)(3a^2 - b) using a^2 - b^2 = (a+b)(a-b)
hope it helps.
Answer:
19.0 cm
Step-by-step explanation:
a^2+b^2=c^2
1^2+b^2=19^2
1+b^2=361
(subtract one from both sides)
b^2=360
(now square root to get rid of the ^2)
=
b=18.97 rounded to the tenths place is 19.0
