1) choice 3
2) commutative property
3) 12x + 8x -3x
common factor of x
x(12+8-3)
or
4x(3+2)-3x
First expression: (-7)/(-4)
Divide. Note that two negative numbers divided will result in a positive answer
(-7)/(-4) = 7/4 = 1.75
First expression: Greater than 1.
-----------------------------------------------------------------------------------------------------------------
Second expression: -(3/2)
Simplify: 3/2 = 1.5
-(1.5) = -1.5
Second expression: Less than -1
--------------------------------------------------------------------------------------------------------------
Third expression: (-8/5) x (-5/8)
Note that two negatives = one positive answer when multiplying
8/5 x 5/8 = 40/40 = 1
Third expression: Neither
----------------------------------------------------------------------------------------------------------------
Fourth Expression: (-5)/(-3)
Divide: (-5)/(-3) = 5/3 = ~1.67
Fourth Expression: Greater than 1

Answer:
-24 a^2 b^7
Step-by-step explanation:
Simplify the following:
-8×3 a^2 b^4 b^3
Hint: | Combine products of like terms.
3 a^2 b^4 (-8) b^3 = 3 a^2 b^(4 + 3) (-8):
-8×3 a^2 b^(4 + 3)
Hint: | Evaluate 4 + 3.
4 + 3 = 7:
-8×3 a^2 b^7
Hint: | Multiply 3 and -8 together.
3 (-8) = -24:
Answer: -24 a^2 b^7
Answer:
x = 2sqrt(5)
Step-by-step explanation:
We can use the Pythagorean theorem to solve
The legs are x and 8/2 =4
and the hypotenuse is 6
a^2 + b^2 = c^2
x^2 +4^2 = 6^2
x^2 +16 = 36
Subtract 16 from each side
x^2 +16-16=36-16
x^2 = 20
Take the square root of each side
sqrt(x^2) = sqrt(20)
x = sqrt(4*5)
x = sqrt(4) sqrt(5)
x = 2sqrt(5)
