Answer:
-16r^2 - 10r
Explanation:
To simplify the expression -2r(8r+5), you can use the distributive property of multiplication over addition.
-2r(8r+5) = -2r * 8r - 2r * 5
First, let's simplify -2r * 8r:
-2r * 8r = -16r^2
Next, let's simplify -2r * 5:
-2r * 5 = -10r
Putting it all together, the simplified expression is:
-2r(8r+5) = -16r^2 - 10r
