PLEASE HELP! i will give the brainliest to whoever answers correctly:)) Please state the like terms in each group:
a) 4w,5w^2, 5z, x^2, -x, 3w, 3v
b) 4x^2, -3x^2, 4z, 2y, y^2, 4w

See below

Step-by-step explanation:

Like terms are terms that have the same variable and the same powers.

A.

4w and 3w are the only like terms. They both have w as their variable and the power 1 as the exponent.

B.

4x² and -3x² are the only like terms. They both have x as their variable and the power 2 as the exponent.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

the answer is:

mean: 6

mad: 2.14
