Answer: :)
Step-by-step explanation: thanks
Pretty sure it's (x-7)^2 - 25.
Um...thats a tough one... well first you have to put the formula together which is pi(10)(26)+pi(10)^2 multiply 10 times 26 then 10 times ten giving us a much more easier equation 260pi + 100pi. we can cross off answer A and answer C just by looking at the simplified equation. now add the two together, giving us 360pi inches^2
Answer:
45 or positive 45
Step-by-step explanation:
Solve for y by setting one equation =to X after that you can substitute the equation into the other one let's set the first one in X= FORM
X-7y=10
-2x+14y=-20
Add 7y to both sides of the first equation to let x stand alone
X=7y+10
Now you can substitute x on the second equation
-2 (7y+10)+14y=-20
Distribute
-14y-20+14y=-20
Add and simplify
Us cancel out =0
-20=-20
0=0
They are the same equations you can also divide the second equation by -2 which would make it look like this
X-7y=10
-2 (x-7y=10)
