Answer:
Step-by-step explanation:
Well we can use the exponential identity: 
The base must be the same for this to work.
So let's combine like bases: 
We can simplify b^2 * b^3 using this identity to get: b^(2+3) = b^5
This gives us the equation: 
But to take a deeper look as to why this identity holds, let's represent b^2 and b^3 by what it really means: 
, so this is really just: 
which can be simplified as an exponent: 
, hopefully this helps you understand intuitively why this identity makes sense.
So using this identity, we can simplify j^2 * j^4 to j^6
This gives us the equation:
6 * 105 = 630
the team scored approximately 630 points in 6 games.
Answer:
1)
32x^2 - 28x - 15
2)
30x^2 + 54x - 12
Step-by-step explanation:
1.
(8x+3)(4x-5)
Using FOIL
= (8x)(4x) + (8x)(-5) + (3)(4x) + (3)(-5)
= 32x^2 - 40x + 12x - 15
= 32x^2 - 28x - 15
2.
(10x-2)(3x+6)
Using FOIL
= (10x)(3x) + (10x)(6) + (-2)(3x) + (-2)(6)
= 30x^2 + 60x - 6x - 12
= 30x^2 + 54x - 12
Answer:
=x^4−2x^3−20x^2+46x−21
if you can give me brainliest that would be great :)
