The answer is X=1.5.
3.5(2.5+x)=14
8.75+3.5x=14
8.75+3.5x=14
3.5x=5.25
X=1.5

Answer: so first you want to do 3.5 x the 2.5 and you get 8.75, then do 3.5 x X and you get 3.5x. now the equation is 8.75 +3.5x=14. take 8.75 nnd subtract it from itself and 14 then you are left with 3.5x=5.25. divide 5.25 by 3.5x and you get 1.5. so the answer is x=1.5

emmainna [20.7K]

Answer:

Step-by-step explanation:

First we multiply x through (y+1). This equals xy +x.

Second we take 3 through (y+1). This equals 3y+3.

Next we take xy + x through (x+2). This equals 2x squared, y + 2x squared.

Fourth we take 3y+3 through (x+2). This equals 6xy + 6x.

#6 :) :) how do you do this ?????
Romashka-Z-Leto [24]
The common difference is -5
right now, a₁₂ = 22

to get a₁, subtract 5 each time you subtract one from the subscript

so

a₁₁ = 17
a₁₀ = 12
a₉ = 7
a₈ = 2
a₇ = -3
a₆ = -8
a₅ = -13
a₄ = -18
a₃ = -23
a₂ = - 28
a₁ = -33



a₁ = -33

hope this helps
