6xy -3x -8y +4
3x (2y - 1 ) - 4 (2y -1)
(2y-1) (3x-4)
Answer: -7/5
Step-by-step explanation:
-4(1/5)⋅(1/3)
Convert -4(1/5) to an improper fraction.
A mixed number is an addition of its whole and fractional parts.
− (4 +1/5) ⋅(1/3)
Add 4 and 1/5
-21/5 ⋅ 1/3
Cancel the common factor of 3.
Move the leading negative in − 21
/5 into the numerator.
−21/5 ⋅ 1/3
Factor 3 out of −21.
3 (−7)/5 ⋅ 3
/1
Cancel the common factor.
Rewrite the expression.
−7
/5
Answer:
8
Step-by-step explanation:
Evaluate 3x^2+x-2 when x=-2
Just plug in x = - 2 into the expression
= 3(-2)^2 + (-2) -2
= 3(4) -2 - 2
= 12 - 4
= 8

Answer:
<u>The correct answer is D. 6r √qr</u>
Step-by-step explanation:
Let's find out the equivalent to √12qr² * √3r
Let's recall that one of the properties of the roots is:
√a * √b = √a * b, for all positive real numbers a and b.
Therefore,
√12qr² * √3r = √(12qr² * 3r)
√(12qr² * 3r) = √36qr³
√36qr³ = 6r √qr
<u>The correct answer is D. 6r √qr</u>
