Answer:
No
Step-by-step explanation:
Substitute 3 in for y
7y-12
7(3)-12
21-12
9
She is not correct, the correct answer would be 9
They are supplementary so they add up to 180
The equation would be x+96+5x = 180
Combine the like terms.
6x+96 = 180
Subtract 96 on both sides.
6x=84
Divide both sides by 6.
x=14
there are 6 combinations but if we change the order we can get more than 6, so the last option is out
the option 2 and 3 cant be because has two reds socks and just exist 1
s, the right option is the first
Step-by-step explanation:
Cir=30π=2πr , thus r=15 , Area=π(r^2)=225 pie meters
The sides of the frame are (12+2x) and (6+2x).
Its area A is 112.
Therefore by equating:
(12+2x)*(6+2x)=112
you can get the answer for x. You will obtain a quadratic equation you have to solve.
