-5 is the answer -20a divided by 4a is -5. If we times 4a by a positive number, we would get a positive number, so we have to times it by a negative number. The number can't have an a at the end as this would mean when we times it by 4a we would end up with a2 -5 x 4 = -20 then we add on the a = -20a
a = -2-4a/3-2 = 8-4a = 8(3-2) times both sides by (3-2)-4a = 24-16-4a = 8-a = 2 divide both sides by 4a = -2 times both sides by -1
Add them together: 3a+4a-a = 6a
You have to multiply base x height - in this case, you obtain (4a)(2a+b). This can't be simplified; you can leave it as it is (factored), or multiply it out to obtain 8a2 + 4ab.
It is an expression of two terms as: 4a+12
The answer is 4a^2.
4a x 3
x2=(4a)(a) x=√4a2 x=2a The geometric mean of a and 4a is 2a
5a or 4a squared
4a*2c=8ac

4a x 4b = 16ab Variables can be multiplied just like numbers.
4a
Factor them. 2 x 2 x a = 4a 2 x 5 x a x a = 10a2 Select the common factors. 2 x a = 2a, the GCF.
