Answer:
Step-by-step explanation:
㏒ 3+㏒(x+2)=1
㏒3(x+2)=1
3(x+2)=10^1
3x+6=10
3x=10-6=4
x=4/3
so A

Based on the social security tax rate and the Medicare tax, the monthly Social security is $109.12 and the Medicare tax is $25.52.
<h3>What is monthly social security act?</h3>
Graham, C. has not reached the $128,400 threshold for social security so the Social Security tax withholding for the month will be:
= Monthly salary x Social security rate
= 1,760 x 6.2%
= $109.12
The Medicare has no limit and so will be:
= 1,760 x 1.45%
= $25.52

Answer:
The answer is 41
Step-by-step explanation:
400 = 900 + 625 - 1500 cos x
400 - 1525 = -1500 cos x
-1125 = -1500 cos
cos x = -1125/-1500
x = cos⁻¹ 0.75
x = 41.409622109
x ≈ 41°
The expression that is a prime polynomial is:
B. 
.
<h3>What is a prime polynomial?</h3>
A prime polynomial is a polynomial that cannot be factored.
In this problem, item b gives a prime polynomial, as:
- In item a, 3 is a common factor, hence the polynomial can be factored.
- In item c, x is a common factor, hence the polynomial can be factored.
- In item d, the polynomial can be factored according to it's roots.

Answer:
g = 61.
Step-by-step explanation:
g + 9 = 70 Subtract 9 from both sides of the equation:
g + 9 - 9 = 70 - 9
