First you had to expanded form.

$-4(2a+5)=-8a-20$

$9a-8a-20$

Finally you can also add by similar to elements.

$9a-8a=a$

$a-20$

Final answer: $\boxed{=a-20}$

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

A number that has a digit in the tenths place,hundredths place,or beyond

nadya68 [22]

A number that has a digit in the tenths place, hundredths place or beyond is called decimal numbers. Any number after the decimal point is called decimal number, it value always started in tenths place value, then followed by hundredths, then thousandths, then ten thousandths, then hundred thousandths and so on. It is still the same with giving place value in whole number. The only difference is, its value decreases as it becomes away from the decimal point.
