2. Simplify these expressions
a 6ab + (-3x) + 2ab
b. 12x + 4y + (-3x)
c 6w + (-2y) + 3w
d 4abc + (-9abc) + 10d

Step-by-step explanation:

a 6ab + (-3x) + 2ab

we have  6ab + 2ab - 3x = 8ab - 3x

b. 12x + 4y + (-3x)

we have  12x - 3x + 4y = 9x + 4y

c 6w + (-2y) + 3w

we have  6w + 3w - 2y = 9w - 2y

d 4abc + (-9abc) + 10d

we have 4 abc - 9abc + 10d = - 5abc + 10d

Here for you.

other answer is correct. i had used the radius of the radius somehow. a website:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
