5 0

$\bf f(x)=-5x^2+2x-1\implies f(a)=-5(a)^2+2(a)-1
\\\\\\
f(a)=-5a^2+2a-1
\\\\\\
-f(a)\implies -~[-5a^2+2a-1]\implies 5a^2-2a+1$

Select the expressions that are equivalent to 8(6m).

$\textsf{Hey there!}$

$\text{Select the expressions that are equicalent to 8(6m)}\downarrow$

$\text{We DON'T have any like terms so we CAN'T pair them off!}$

$\mathsf{8(6m) \rightarrow 8 \times 6 \times \ m}\\\mathsf{8\times 6 = 48}}\\\mathsf{48\times\ m = 48m}\\\\\\\boxed{\boxed{\mathsf{Answer: \bf{48m}}}}\checkmark$
