2+(x+4)= ?
So it really is: 2+1(x+4)=0
You distribute the 1 to the x+4
2+ 1x +4= 0
Combine like terms
1x+ 6=0
Subtract six on both sides
1x=-6
Divide by 1 on both sides
x=-6

Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.

P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction

Knowing this, we should start by doing the equations <em>within </em>each parentheses.

$(-7 - -9) *(8 + 2)$
$(2) *(10)$

So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:

$(2)*(10) = 20$

20 is the answer.

Answer: $ 14736 (approx)

Step-by-step explanation:

Since, Maturity value is the amount payable to an investor at the end of a holding period of debt instrument.

And, It is defined as, $V= P(1+r)^n$

Where, P is the principal amount,

r is the interest rate

And, n is the time period.

Here, P= $4,400 r= 12 % and n = 172/365

Thus, Maturity value for this loan,

$V = 4400(1+12)^{172/365}$

⇒V= 4400 × 3.34908932078 = 14735.9930114 ≈ 14736

To get the units needed, divide the given number of items needed shown in the above portion of table, with the package size given in the below portion. Then multiply with given prices. Round off the numbers to whole numbers.

Now, money needs to be spent in Quality Groceries-

$(5*15.5)+(2*6.23)+(7*3.79)+(2*2.75)+(2*4.33)+(5*7.55)$

=$ 168.40

Now, money needs to be spent in Fresh Market-

$(7*12.4)+(3*4.99)+(7*3.55)+(3*2.55)+(2*5.55)+(5*6.99)$

=$ 180.32
