A. -(a+5)
Because the negative sign is outside the parenthesis, multiplying by -1 just removes the negative sign:
-(a+5) * -1 = a+5
B. -(-x+31)
Apply the distributive property:
-(-x+31) becomes (- -x +31) which simplifies to (x+31)
multiply that by -1 to get -x+31
C. -(4x+12)
Because the negative sign is outside the parenthesis, multiplying by -1 just removes the negative sign:
-(4x+12) * -1 = 4x+12
Answer:
We need to sketch the problem first.
Find the size of angle R.
One member travels a distance of 12km due north. Another team member heads 50degree east of north and travels a distance of 10km.
If se substute 50° of 180 we have
180-50=130°
The distance between the two team members is the missing side.
We know two sides and included angle, so we use the cosine rule.
A2+b2+c2-2bcCosA
= 102+122-(2x10x12xcos130°)
=100+144-(-147.08)
=100+144+147.08
=391.08
A==SQRT391.08
=19.775
19.7km

Answer:
Step-by-step explanation:
Notes payable = $348000
Payable interest = Note payable × Interest rate × (no of months used/no of months in a year)
348000*(8/100)*(3/12)
= 3480*8*(3/12)
= 83520/12
= $6,960
The total cash will be $348000 + $6960 = $354960
Therefore in the account statement, om the debit side we will have the Notes payable and payable interest, while on the credit side we will have total cash.
This can be seen as attached.
24+3.1+(-44)+(-8.2)+63= 24 + 3.1 - 44 - 8.2 + 63= 87 + 3.1 - 44 - 8.2= 43 + 3.1 - 8.2= 43 + 3.1 - 3.1 - 5.1= 43 - 5.1= 43 - 3 - 2.1= 40 - 2.1<span>= 37.9</span>
