Answer:
p = 8000 + 2(6000)
20000
Step-by-step explanation:
Given that:
Profit in 1988 = 6000
Profit in 2003 = 8000 more Than double the profit made in 1998
Hence profit in 2003 (p) can be expressed as :
p = 8000 + 2(6000)
Hence profit in 2003
p = 8000 + 12000
p = 20,000
Factor out the common term x
x(x^2 + 18) = 0
Solve for x; How?
Ask yourself: When will x(x^2 + 18) eqal zero?
When x = 0 or x^2 + 18 = 0
Solve each of the 2 equations above
Thus, x = 0, ±3√2i
Hi there!
24. 6x² + 19x + 3
1 3 multiply 6 × 3 = 18
6 1 multiply 1 × 1 = 1
18 + 1 = 19
(x + 3)(6x + 1)
I just simply found the two factors of 6 and 3 that can add up to 19.
This way is useful when the a and c don't have much factors.
27. 5y² + 13y + 6
1 2 5 × 2 = 10
5 3 1 × 3 = 3
10 + 3 = 13
(x + 2)(5x + 3)
30. 16x² + 16x + 3
For this one, 16 has a lot of factors. So you can try "Grouping" method.
You multiply 16 and 3. 16 × 3 =48
Find the factors of 48 that can add up to 16.
Hmm.. 12 and 4 would be great.
Then rewrite the equation.
16x² + 12x + 4x + 3
We would factor 16x² + 12x and 4x + 3 separately.
16x² + 12x 4x + 3 can't be factored more.
4x(4x + 3) 1(4x + 3)
(4x + 1)(4x + 3)
So your answers are....
24. (x + 3)(6x + 1)
27. (x + 2)(5x + 3)
30. (4x + 1)(4x + 3)
Hope this helped!!
Answer:
Step-by-step explanation:
10^8
it means multiply 10 8 times so
10*10*10*10*10*10*10*10
=100000000
