Answer:
Step-by-step explanation:
g(5) = 5^2 - 4 = 25 - 4 = 21
f(21) = 5(21) + 2 = 105 + 2 = 107
Answer:
BC=23
Step-by-step explanation:
Use sine rule:
x/sinX=y/sinY
BC/sinA=AB/sinC
BC/sin61=9/sin20
BC=26.3142396015*sin61
BC=23.0149525338
The interest for each method will be:
- Previous Balance Method = $37.50
- Adjusted Balance Method = $36.88
- Average Daily Balance Method = $2966.67
<h3>How to calculate the interest?</h3>
The Previous Balance Method will be:
= PTR
= 3000 × (1/12) × 0.15
= $37.50
The Adjusted Balance Method will be:
P = 3000 - 50 = 2950
t = 1/12
r = 15% = 0.15
I = 2950 × (1/12) × 0.15
= $36.88
The Average Daily Balance Method will be:
= (3000 × 10) +(2950 × 20)/30
= 89000/30
= $2966.67

Step-by-step explanation:
7(x + 6) = 42
<em>distributive property</em><em>: a(b + c) = ab + ac</em>
(7)(x) + (7)(6) = 42
7x + 42 = 42
<em>subtraction property of equality</em><em> (subtract 42 from both sides)</em>
7x + 42 - 42 = 42 - 42
7x = 0
<em>division property of equality </em><em> (divide both sides by 7)</em>
7x : 7 = 0 : 7
x = 0
It is given in the question that
The area of a square sandbox is 46 ft.².
Let the length of the side of the square sandbox is x ft .
And formula of area of square is
Substituting the given value of area
We need to get rid of square, and for that we take square root on both sides
And the formula of perimeter of square is
