Ich expressions are equivalent? select equivalent or not equivalent for each pair of expressions. equivalent not equivalent 3(a+b) and 3a+b 4(x+2y) and 8y+4x

3(a + b) and 3a + b - NOT EQUIVALENT because

3(a + b) = 3a + 3b

used distributive property a(b + c) = ab + ac

4(x + 2y) and 8y + 4x - EQUIVALENT because

4(x + 2y) = (4)(x) + (4)(2y) = 4x + 8y = 8y + 4x

used distributive property a(b + c) = ab + ac

and commutative property a + b = b + a

3(a+b) is not equal to 3a+b

4(x+2y)  is equal to 4x+8y

Step-by-step explanation:

3(a+b)  

Distribute

3a+3b

This is not equal to 3a +b

4(x+2y)

Distribute

4x+8y

This is equal to 4x+8y

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week
