Answer:
After 10 years the investment A will be bigger than investment B.
Step-by-step explanation:
In Investment A, 50 increases each year by 8% and in investment B, 60 increases by 3 each year.
If after x years the investment A will be equal to investment B, then we can write the equation as

⇒ 50 + 4x = 60 + 3x
⇒ x = 10
Therefore, after 10 years the investment A will be bigger than investment B. (Answer)

Step-by-step explanation:
There are three possible cases:
1. Point N lies between M and P, then MN + NP = MP. Consider needed difference:

2. Point N lies to the right from point P, then MP + PN = MN. Consider needed difference:

3. Point N lies to the left from point M, then NM + MP = NP. Consider needed difference:

C= πd, where C means circumference and d means diameter. 0.75 is the diameter of the pond, so 3.14 × 0.75 gives you 2.355mi.
You walked the diameter while your friend walked the HALF circumference. (2.355÷2) -0.75 is your answer
Answer:
(3x + 4)(x - 1)
Step-by-step explanation:
3x^2 + x - 4
use middle term break method
we need two number which gives 12 when multiplied and 1 when subtracted
3x^2 + (4 - 3)x - 4
3x^2 + 4x - 3x - 4
x(3x + 4) -1(3x + 4)
(3x + 4)(x - 1)
3x-6+4=-20
- add 6 to both sides
3x+4=-20 +6
3x+4=-14
- then subtract 4 from both sides
3x=-14 - 4
3x=-18
- then divide 3 from both sides
-18 divided by 3 = -6
x= -6
