Pl simplifiy a^2 ⋅ a^m

a^(2+m)

Step-by-step explanation:

We can simply add the exponents together because they have the same base which will give us a^(2 + m).

a^[2+m]

Step-by-step explanation:

When multiplying two polynomials with the same base but different exponents, we add the exponents because

a^m*a^n

= a^m+n

So,

a^2*a^m

= a^2+m

Since it can't be solved anymore this is the simplest form

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
