So the area of a rectangle is Length x Width.
A = (L)(W)
Substitute the information given:
4x^2 + 20x + 16 = (L)(2x+8)
Isolate L by dividing 2x+8:
(4x^2 + 20x +16)/ (2x + 8) = L
If you divide:
L = 2x + 2.
Answer:
A) (-3, 3) B) (-1, 1) C) (-2, 3)
Step-by-step explanation:
-8=-(x+4)
remember the invisible 1
-8=-1(x+4)
distribute using distributeiv porpety
a(b+c)=ab+ac
-1(x+4)=-x-4
-8=-x-4
add 4 to both sides
-4=-x
mutily both sides by -1
4=x
Answer:
The correct answer is v(t) = (principal × time × 0.02) if calculated simply and v(t) = Principal ×
where v(t) is the interest after t years .
Step-by-step explanation:
Principal amount invested by Shota is $2000.
Interest is earned at 2% per year.
Time for which the principal is invested is t years.
Therefore let the total interest be v(t) dollars in t years.
Case 1: Simple Interest.
v(t) = (principal × time ×
) = (2000 × t × 0.02) = 40t
Case 2: Compound Interest.
v(t) = Principal ×
- Principal = 2000 ×
- 2000.
Answer:
(-2, 5/3)
Step-by-step explanation:
Step 1: Write out systems of equations
y = 2/3x + 3
x = -2
Step 2: Substitution
y = 2/3(-2) + 3
y = -4/3 + 3
y = 5/3
Step 3: Write solution
(-2, 5/3)
