Expand −4(6a − 5) .(1 point)
Expanding -4(6a - 5) yields:
-4 * 6a = -24a
-4 * -5 = 20
Therefore, -4(6a - 5) = -24a + 20.
To expand the expression −4(6a − 5), we need to distribute the −4 across the terms inside the parentheses.
We can do this by multiplying −4 with each term individually.
First, we multiply −4 by 6a:
-4 * 6a = -24a
Next, we multiply −4 by −5:
-4 * -5 = 20
Putting it all together, the expanded form of the expression −4(6a − 5) is:
-24a + 20
To expand the expression −4(6a − 5), we need to apply the distributive property. The distributive property states that for any three numbers a, b, and c, (a × (b + c)) is equal to (a × b) plus (a × c).
In this case, we have −4 as the value of a, and (6a − 5) as the value of b.
So, we apply the distributive property:
−4 × (6a − 5) = (−4 × 6a) + (−4 × −5)
First, let's simplify (−4 × 6a):
−4 × 6a = −24a
Now, let's simplify (−4 × −5):
−4 × −5 = 20
Putting it all together, we have:
−4(6a − 5) = −24a + 20
